I understand about the gamecenter link, it doesn't affect me as much because I see 5 Tvs at once at my friends house w/ satellite, but sometimes I leave his house early and check updates of 4 games at once
A friend of mine chooses not to go to his house and monitor games online, he was able to see play by play updates of all the games at once, now he would have to open 8 different gamecenters and not be able to see all at the same time, ya know?
