Have anyone tried Gree. The mobile social platform bought over openfeint. They have a sdk for Unity but when you call Gree.Authorizer.Login to promot user for login. A login window pop-up and there is no option to close it! So if this window pop-out, user HAVE TO has a Gree acount to login otherwise its stuck there forver. They just published a new SDK today 25 June, and the issue is still there.
How could it possbile?? Should I abuse those Jpas (Gree company) or am I missing something???
Quick question about the issues you’re having - are you running iOS or Android? Within the Unity plugin, there is an option for ‘enableGrade0’ which allows your players to play the game without needing to login, however this feature is unique to iOS.
Good luck, and let us know how this works out for you!
