I flip Kitties too, decent concept. They recently released some new "rare" kitties which are selling at 1eth a piece, the finaly Gen 0s run out at the end of this month then we will see if the games going to take off or fail 
I have spent my money for kitties and that worth nothing right now. This game suck it doesn't have an interesting gameplay. DEX is the only best dapps right now and remember about 0x protocol and it's even better than dapps game.
