Crafting

Introduction

When a game needs you to create items, it is common for them to have you find the materials required to craft it. Crafting is a mechanic that every game does differently and there are a lot of good examples out there. When most people think of "crafting", they might think of Minecraft's implementation, but that won't work for every game.

What is crafting?

Crafting is a mechanic that cannot stand on its own. It is a mechanic that the player can use to help progress the story. The game loop for crafting is: external - internal - external. Crafting starts with an external mechanic, like exploration and collecting resources. Then, the player uses those resources to interact with an internal mechanic, like brewing a potion. Finally, the player uses that craftable item in an external mechanic, like throwing a poison potion at an enemy.

In some games, crafting feels just like another shop. A lot of games use a very similar process for crafting as a shop, where you have your "currency" and you tap a button, and you "purchase" an item. For a crafting system to be good, it needs to feel special, like you are making a difference. The point of crafting isn't to inconvenience the player - it is to give the player a choice. The player needs to be able to make a decision to further the game in their style.

Examples of Different Implementations

Minecraft

Minecraft is a game, in which, the entire purpose is to collect items and craft items - hence the name MINE and CRAFT. Minecraft has combat, bosses, farming, biomes, and many other mechanics; but the goal is to do something to get an item, to craft it, or turn it, into a different item.

Minecraft's crafting mechanic is fairly complex compared to other games, which was made easier in newer versions. The basic idea is that you start off with a 2x2 crafting grid, which allows you to play 1-4 items in it, in a specific arrangement. At a certain point, the player can create a specific item, called a Crafting Bench, to give them a 3x3 crafting grid, however, they have to go to the location of one of the crafting benches to access it.

Minecraft has a similar mechanic for different types of crafting. They have a "furnace" which can cook/smelt items, for example, 1 piece of coal can cook 8 pieces of raw beef to make 8 pieces of cooked beef. Then there is the brewing stand, blast furnace, smoker, and many other workstations that can convert one item into another. Each interactable utility block in Minecraft is used differently, has its own purpose or ruleset, and is required for advancement throughout the game; but it is just using the same crafting mechanic in different ways to build out the world.

In later updates, Minecraft added a submenu to the crafting UI that allows you to search up what you are able to craft and it will auto-populate the crafting bench in the proper order. Some of the community thought this change was needed because the list of craftable items continues to grow and some of the recipes and steps gets fairly complex. The crafting grid is still there, so the members of the community who don't like the change can still use the "old" mechanic.

Potion Craft: Alchemist Simulator

Potion Craft: Alchemist Simulator is a game that is almost entirely crafting. This game's primary mechanic is crafting different potions to sell. There are different "Picture" scenes you can go to and collect items, people to talk to, and a shop to buy stuff; however the main scene has a couple different tools, like a mortar and pestle and a cauldron. The crafting is very involved, you have to drag a raw material into the mortar and then you grab the pestle and actually grind the material. The cauldron is similar where you have to grab the ladle and physically move it back and forth to stir it.

Far Cry: Primal

In Far Cry: Primal, crafting is simple. As you progress through the story and unlock different buildings and NPCs, you unlock more crafting recipes. You need to gather materials around the environment. Most crafting recipes require three different items and when you have the materials necessary, you hold the craft button for a few seconds. The player doesn't need to remember anything or do anything other than just gather the material and have the recipe unlocked.

Design Considerations

What makes a crafting mechanic good?

Every game will implement crafting in a different way. For crafting to be good, it needs to be designed specifically for the game it is in. A lot of games make their crafting feel like a shop interaction or just clicking through menus, because someone, somewhere, decided that "players like crafting" and "our game needs crafting", but that takes out the joy in the system.

Not every game needs crafting. There are games that if you took out their crafting mechanic, players wouldn't notice. A big problem in open-world RPGs is that players might spend hours looking for a specific material and by the time they get back to the crafting table, they have found a better item. In Ghosts of Tsushima, crafting doesn't require any decision-making. Wood upgrades the bow, metal upgrades the swords, etc. You collect everything and once you can upgrade something, you do.

Take Left 4 Dead 2 for example, according to SteamCharts, between 20,000 and 42,000 online players at any given time [July 9th, 2024]. This is a game that was released in November of 2009. Steam has 869,000 total reviews and 847,000 of them are positive. Objectively, this is an amazing game that is still very popular. Many of the mechanics we have today, including crafting, are not present in this game. This is a game whose pacing and item collection define it and crafting would mess up a lot of its balance.

The Last of Us 2 does a better job of making crafting feel important. They limit the resources the player can carry AND they make you choose what the player wants to craft. For example, rags can be used to make med kits or Molotovs, choosing between offense or defense. Most good implementations of crafting make the mechanic seem important. You want the player to be able to choose what to craft, you want it to mean something, and you don't want it to be a grinding mechanic.

In Skyrim, most players sit there and craft thousands of iron daggers. To be able to craft better equipment you need to level up your crafting skill. Progressing through the game you always get better equipment from shops and loot than what you can craft, up to a certain point, and at that point, players will spend hours upon hours just crafting iron daggers to get "caught up". Crafting in Skyrim is a lot of grinding with no gain for however many hours it takes to collect thousands of daggers worth of supplies and to craft the daggers (not to mention the carry limit) - leaving the whole mechanic less than ideal.

What Skyrim does right is that crafting takes time. When players can pause the game in the middle of a fight, craft a few med kits, heal themselves, and continue the fight; it's just a menu interaction and that takes away from the combat mechanic. Skyrim requires the player to go to a specific place, select the item they want to craft, and there is a small cutscene of your player crafting the item. That makes it feel important.

Terraria and Monster Hunter: World arguably have some of the best crafting mechanics. Terraria doesn't use skill trees, levels, points, etc. The crafting system is solely based on progression through the game, there's above-ground loot, below-ground loot, enemy drops, etc., and everything is uniquely named. It has a large crafting system and the player is in control. Monster Hunter: World has an amazing progression tree for armor and weapons based on loot from monsters that the player kills. The progression makes sense, is in line with the story, and isn't restrictive. Both games have one, very minor, flaw. In Terraria, crafting a legendary item feels the same as crafting a basic item. There is no special animation or sound effect. In Monster Hunter: World, the player doesn't actually craft weapons or armor. They put in an order and the blacksmiths make it. As far as the feel goes, the blacksmiths always look disappointed in the character, even if its high-level equipment. Also, it's disheartening to the player to have blacksmiths do all of the crafting. As Noia Dev says in their video, "If anyone is going to craft a weapon called Demonlord Hellfists, it's going to be me".

A game that gets a lot of hate for their crafting system is Warframe. To try to convince players to pay real-life money for their in-game premium currency, Warframe has timers in their crafting system. Some are 60 seconds. Others are 3 real-life days. To put it into perspective, players will spend real-life weeks collecting all of these resources to craft this item they need, just to have it make them wait 72 hours for it to craft. Developers need to make money, but there are better ways to encourage a premium currency that doesn't push players away from your game.

How can I change the crafting difficulty?

Crafting difficulty is tied to the other mechanics surrounding it. You can make crafting easier or harder by modifying the exploration and loot mechanics to make rarer items more common or provide tooltips and hits to the player on where to find specific items. Subnautica does this by allowing a player to scan items to get additional information and different types of items are biome-based, so if a player needs a specific type of item, they know where to go to find it.

Another way to change the difficulty is to modify the number of resources it takes to craft. This isn't just raw materials - this can also include a character's attributes. If your game has an "energy" mechanic, you can make crafting use energy - or if the player does a lot of crafting it can start to use a character's health (due to "mistakes" made in the crafting process).

In Stardew Valley, the player has to interact with different mechanics to unlock new crafting recipes. The character can learn new recipes from leveling up different skills, befriending NPCs, completing "special orders", and many other things. Limiting a crafting recipe behind a different - but related - mechanic can certainly make the recipe feel more rewarding and challenging. Do be mindful of what recipe they unlock versus where they are in the mechanic, the crafting recipe should be better than what the player will get from that mechanic.

If your game is not open-world, you can limit access to crafting. In Doom, there is a weapon upgrade mechanic but the machine to upgrade the weapons is rare AND hidden; so when the player can find one, it feels very rewarding, and the upgrades significantly improve the weapon. When you make a mechanic that is hard to utilize, you want the reward to be worth it.

Not all crafting has to be from gathering resources. You can make crafting more difficult by requiring the player to master multiple different aspects of the game. You can section resources off by requiring them to be purchased from the shop, from killing different kinds of NPCs, foraging, mining, panning in a water source, fishing, etc. You can make any other mechanic a source of specific types of resources for crafting.

What should I avoid within a crafting mechanic?

The biggest thing to ask is if you need a crafting mechanic in the first place. What would it add to the game? There is nothing wrong with avoiding crafting all together, especially if it doesn't add anything to the gameplay and is just another thing for the player to learn.

You want to avoid wasting the player's time. Pointless crafting mechanics will make the player feel like the game doesn't value their time. You should avoid crafting mechanics that don't give them a choice. To reference The Last of Us 2 again, the game has a limited inventory and crafting resources are sparse, meaning that the player will need to use the resource that they picked up very quickly after getting it, and everything serves multiple functions. In that game, when a player picks up a rag, they need to decide immediately if its going to be for healing or for attacking.

Another thing to avoid is making crafting not powerful enough. A lot of games will make the player search for a specific item or level up crafting to a certain skill level before they can craft an item, but by then, that player picked up a better item from somewhere else, like a shop or loot, making the mechanic useless.

Players tend to not like crafting mechanics that involve a lot of grinding. Keeping the mechanic a bit more simple is usually better. If it takes 10 hours to find, refine, combine, and temper an item, it better be worth those 10 hours.
