And it's a good point - I could see it being a part of the game world. I wouldn't set it as something that can happen through normal wear and tear, or even through a decent amount of abuse. But it would just make sense that most items would have limits - that if you "break" an item beyond a particular point too many times and continue to use it that way for too long, it would eventually become irreparable. I wouldn't want to see it punish relatively normal gameplay - only as something that kicks in if an item is obviously and regularly abused - so I'm not sure how much it would add to the game, but it's still an intriguing idea.
