I doubt I'll miss Xbox Live too much, but I'll certainly try and get it working.
It's a bad year to go to Uni as a gamer. So much is coming out in the next 6 months. I'd love to get MW3 on the Xbox, as well as Fifa 12 but it wouldn't be worth it without online play. Skyrim comes out too, but thankfully that's single player.
I'd be interested in seeing a few things on the computer. Apparently the original Guild Wars is permitted to connect via RESLAN, so fingers crossed that Guild Wars 2 will be able to connect as well.
Modern Warfare 2 on the PC apparently connects, so again, hopefully MW3 will on the PC.
