That is my referral link. You can delete the referral part if you want I guess.
The game is in development. Its pretty fun. It's similar to mafia wars or other similar MMORPG games of the like.
You can make bit coins off of the various lottery and gambling games they offer. Join gangs, etc... You know the drill for these types of games.
You can trade in BTC for in game cash and items too, but you don't have to
I feel like the game is pretty fun.
