SP: I must go with Halo: Reach just because I absolutely loved the story, it made the spartans look human and that they need to rely on each other, rather than just the gun-slinging, lone-wolf that was masterchief. and I found R2's story kinda weak.
MP: I would give this to Resistance 2, i like R2's huge maps and player count.(though Halo: Reach MP was great as well)
but I'm going to give this to Halo Reach.
