Talk:Game Center/@comment-124.82.90.13-20120721022711

When I first got this app they asked me to log I to gamecenter, but when I opened it the second time it didn't ask me and I was able to play. Now I was thinking maybe I should log in to get friends and stuff, but would I loose all m stuff if I did? I'm level 13 and I really hope I can keep all my stuff... Please help.
