I wish I could bro. Sounds like everyone here is hailing this as the rebirth of a fictional character called Jesus.
I want in on this camaraderie, and show my amazing skills. I think my playstyle suits Halo.
Getting a 360 and Live is insurmountable however. I'm not being a cock, but I just don't think I'd need the console for anything but this gem. Plus I'd come across as a bellend to friends if I owned both systems.
Essentially I'm holding out on R3 to be awesome, which it will be. But it's still far removed from the same type of FPS. I know for one the campaign in Resistance will be better. I found Halo campaigns, bar 1, to be horrendously boring.
The multiplayer of this looks SICK though. If you don't take an avid interest in FPS you may be hard pressed to find a reason why this is good. But when I watch footage. All I see is incredible possibilities and tremendous fun.
