I played Halo 1 & 2 on PC and counldn't really see what the fuss was about, maybe because by the time they came out they had been outdone many times over on the PC. Also, as I don't play much multiplayer most of my opinions are based on SP.
Halo 1: 7
Halo 2: 6.7
Halo 3: 7
Halo Wars (based solely off the demo): 8
I'll probably buy Halo Wars but I'm not going to bother with Halo 3 as after Halo 1 & 2 I really don't see the point me getting it except to play the campaign in co-op when I have someone round.
