I've been wrestling with the same problem. I've decided that my approach will be to register, unseen to the user, an anonymous account when they first need an identity on the server (eg. when posting their first high-score). Then, after they have continued to use the app for a time (eg. when they have posted a certain number of scores) they will be invited to associate credentials with the account (in my case a username and password) with text that explains the benefits (ie. they can carry that identity over to other devices and between other applications I write).
My aim is to avoid pestering users who are just trying-out the app without letting active users miss out on the benefits of registration (or penalizing them for delaying their registration since everything they have done with the app prior to that will remain associated with the same account). A background server task will periodically wipe abandoned anonymous accounts. It's definitely more work work this way, but I think it's favourable to the users. I'd be interested to know if anyone else has found a good solution that's less work. Tom.
