All the website really says is "Here's a solution, just install our code in your game. It's easy!"
If the problem is just that I don't have third-party code in my game then I guess you got me. Otherwise I'd probably need to know what problem is being solved and how.
From reading your API page, it looks like you're building something sorta like Xbox Live (and now Open Feint and Gamecenter). Managed leader boards, achievements, ,maybe buddy lists and invites, etc. Is that correct?
