People's experiences of Game Centre...worth it?

Hey up people!

So in my new game I'm thinking about implementing Game Centre, but I don't know too much about it.  My assumptions is it records hi-scores and allows leaderboards for your game.  Which I like the idea of. 

Does it just record hi-score or can it record say a time? As in if the aim of a game is to see how long you can stay alive...

Just wondering what people's experiences of it are.  Was their any advantages of it? Did it get used? Effect the amount of downloads? Easy to set up and implement? That kind of thing

Cheers

Game Center definitely gets used, but another reason to consider it is, Apple will feature games that use Apple-related services more easily, so it's definitely worth it.

You don't want to miss out on a potential front page feature by not having GC.

Aah that's great to know!! Thanks mate!

I didnt know that... time to use GC instead of regular leaderboards...
