Also, here is some info they just posted on using Game Center to transfer games - WARNING - It looks to me like it would be VERY easy to lose accounts forever if you have multiple accounts on multiple devices that share one Game Center account! I'd love to ask Gree how to manage this (and I have), but all these posts say "Article is closed for comments."
