Hi Hi will be releasing a lite and full version of my game and was wondering if they can share the same game centre leader boards. Is the possible? Thanks
I vote for yes. You can even play multiplayer games with matchmaking across apps now. Create a game center group on itunes connect and add all apps who are supposed to share leaderboards. Read Apple's docu on Game Center and iTunes connect for the details.
Mark is correct - I share leaderboards and achievements between the free & paid versions of Critter Panic. But I will warn that it's easier to set this up if neither game is actually released yet. I merged things after the fact and the process was a bit haphazard. To top things off it took Apple over a month to fix a server-side issue that broke achievements in the paid version. Hopefully they've ironed out the bugs since then.
