StarDunk is the first game to migrate old achievements to Game Center
An app that doesn't forget
Plenty of games have now gone live with support for Apple's Game Center, but Godzilab's StarDunk is the first one I've seen that retrospectively adds your old scores into the new system.
Other games such as Fieldrunners and Flight Control force you to start again building up your position on the leaderboard from scratch.
Data to the foreIn the case of StarDunk, it originally launched using ngmoco's Plus+ system, which, in fact, it still uses for its online multiplayer servers.
However, cleverly, Godzilab has managed to make sure the old in-game achievements map across to the new Game Center achievements. For some reason though, high scores haven't been included in this migration.
Asking around, it seems that most developers should be able to do something similar with their old games. Some networks such as OpenFeint and Scoreloop are providing developers with migration tools to help them out.
Angry Birds developer Rovio also told us it would be making sure it copied across players' data from its Crystal social network to Game Center too. The update to support Game Center within Angry Birds hasn't been released yet.
