So,
I've send a FR to radar about this...
22976399
...but I thought I would mention it here as well...
For a racing game, I would like to store a race trajectory (ghost car) with a score submission.
GameKit has a provision for GKScore.context, but this is a 64b identifier only, and storage of context is left up to the developer.
I think it could be a service valuable to developers to have a place to store a score context.
GameKit (GameCenter) should provide this storage, I think, so that the developer does not have to rely on third party servers.
