Stat tracking app for r.p.g. game

[RollOutOnMe]

I need some initial advice on how to go about developing an app that tracks player stats and creates a leaderboard and some other game related info.

Is the only way to do this with a public API, and if they do not have one, are they any other ways, other than having the game makers give me access to their API?

I moved this from the Android Apps forum to the Developers Lounge, since the former is intended for developers to promote their apps.
