I liked the crafting system in Fallen Earth; I know its a ****ty game.
There were the usual skills, such as weaponcraft, armorcraft, first aid, mutagenics, munitions, cooking, science, etc. For gathering base resources, this game did have the typical nodes, but the game also had scavenging as a trainable skill that allowed you to gather additional resources.
your proficiency or ease on learning a specific skill and how high you could take it depended on your attribute spread; it was usually a combination or 2 attribute totals and character level that established your "cap". You didn't just automatically gain a ton of new crafting options by gaining Weaponcrafting 50 or 75.
Weaponsmithing, for example had a very broad crafting base, everything from hunting knives and axes, to hockey sticks and grenades. Within each weaponsmith subset, axes for example, you had tiers. Axe 2 for example would open up a new category of axe types, more again in Axe 3. Each skill train within the tree branches the tree farther, and each skill must be learned from a book that may be purchased or quested for.
Crafting occurred in a queue. It may take 4 minutes to craft a low level item, and an hour for high level items within each Tier. You could continue to play the game as your crafting queue counted down to completion.
it was one of the better systems I've seen
