First of, I do have to congratulate every one here, and elsewhere that reported this issue.
Now however, all we can really do is wait.
Once anything with games hits the news, it tends to spread like a wildfire. If it's good news, gamers swarm to whatever it is.
If it's bad news (like this) gamers don't stop yelling and a lot of them are real easy to loose and real hard to get back.
Apple loves to say they have all these apps on the marketplace, especially games. Now however, a lot of games are broken because of Game Center. I'm sure Apple is or will be scrambling to get it fixed ASAP as bad news spreads fast.
Totally meant to reply to denisamirright above me.
