This would face some serious design challenges. In order to provide good gameplay you need to be able to regulate the in game economy, which can be tough with a currency that you don't have full control over.
Yep, looking at it I know it'd be one huge challenge so I'm not even sure if it's possible yet. Everything had to have an idea before it was created though. Not all ideas are winners but I thought I'd share this one anyways.
Nice idea. So many things that can be done with BitCoins. Have to do alot of work on your in-game economy tho. Most games have huge inflation issues.
OMG that is so true! XD One time I played an mmo that had been hacked so badly the money was practically worthless so we had to barter in items.
