Had an idea where whenever you create something, it show you the Quality it's going to come out as, and you have the ability to decrease the quality of the item when you make it. Whether or not there's some advantage to doing so, that's up to what's fair. But having the power to control the quality of what I make would be something I would enjoy having.
Though some alternative ideas to the concept:
- Maintenance: Taking the repair concept steps further, that objects have a "maximum quality" and decrease in "current quality" as they decay (or are used). When you repair/maintain an object, it recovers some of it's "current quality", based on the quality of the object used to repair it, but can't recover more than it's own quality. Example: A q50 tanning tub is currently q8/50. You use a q10 board to repair it, and the tub is now q10/50, but you need a q50 board to repair it to full.
- Upgrades: Once you're able to make higher quality versions of something, you could use the same material it takes to repair an object to upgrade it's quality instead (rather than having to make new ones). Example: You have a q10 Tanning Tub, and a q50 board (and appropriate skill to make a q50 Tub), so you just upgrade your tub instead of building a new one (though it may not be a q50 tub, may be like, q20 or 30, requiring more boards to fully upgrade).
- Dismantle: Though I've seen this concept suggested before in many different varieties, the idea of being able to break an item or structure down back into it's crafted parts (or just a fraction of them). However, the recovered parts would have reduced quality from the original (example: a q10 stone axe gives you a q5 stick when you dismantle it).
- Money Talks: The ability to use coins as a substitute for crafting materials when using the above abilities, and a new skill "Marketing", which allows you to obtain lowered quality coins off goods you dismantle (a q2 silver coin instead of a q5 stick from the above scenario). Adds a mechanical use to coins, but obviously creates a strange system of create/destroy to the coinage that may not be what's intended for currency.
