It would be neat to institute a WoW-style coloring system for treasure names. For instance:
- Black for common resources and their recipes
- Green for quality 1 equipment, uncommon resources, and their recipes
- Blue for quality 2 equipment, rare resources, and their recipes
- Purple for quality 3 equipment, exotic resources, and their recipes
Missing from this is a way to classify improvements, which would probably need to be done by level. Also, it'd be fun if equipment could become gold after it becomes untradeable when it reaches 100 gold in value.
