How about this - a WOW type of game in which weapons are forged in limited supply (and controlled by their very own block chain!) those weapons gain power with use and time thus increasing in value and can be sold and traded in the game?
I can't immediately grok the game balance implications, but on its face it's a brilliant idea. RND would determine if a block would forge coins, a weapon, a spellbook...
How many 'variants' can (should) be forged in a block? Would tx fee in the block affect the RND or what was forged? What's the game logic behind an item gaining power with use? (most mechanics use durability, which isn't quite the opposite of what you're talking about, but close).
At what point do I/we/the voices in my head move this off-thread and over to a nxtopia web forum?
