Game Center for apple has every single multi player game in its lobby. It's all located in the same place and you can see who is playing what. Regardless of developer or game company.
i got it
...one lobby were all users are visible with the games from Matrix / Slitherine they have installed (at the time of log-in ) ...so you first see who is online, and what he has available, and then chat about what game to start, then moving on to a 'sub-lobby', let's say: a CoH room (lobby) or a CC:PitF room(lobby), etc.
the idea behind this is: the individual games lobbies are often empty and so you can 'negotiate' about what game to start, because one gamer might be willing to agree to play a different game instead of non, or instead of waiting half an hour for anotherone to show up, who might want to play his first choice
Thank you Mike. Yes the above is exactly what I mean.
