In other words your trying to make your own Gamecenter/Oppenfeint/TA app.. Good luck.. There use to be alot more of these than they are now, most of those just failed because no one was going there anymore. I think people just want a better gamecenter.. But not anything diff than gamecenter..
It's not a app it's a site. It doesn't look like a GameCenter/ OPenFeint or TA app. If you want to see it you can mail to [email protected]
Gameloft released something like that yesterday but gameloft sucks ass because they are worse than zynga. It's called gameloft live
