I've really liked the Halo 2/3/ODST online ( ODST for the co-op horde mode), it's always been solid and balanced, the only problem I ever had was that it's only 30fps. I so much more enjoyed COD4/6 because of the 60fps. I'm assuming Reach is only 30fps too.?? Halo3 just feels so slow after playing the MW games.
