halo 2 was the best.. everything about it was perfect. halo 4 needs what halo 2 has like: out of campaign map exploration, alot of easter eggs, alot of fun glitches (super jumps!), crosshairs didnt expand when shooting, br was legit, long campaign, turf, fun campaign, and everything ppl said that was positive about halo 2 said on this thread!
so i put classic, and i have a feeling the *new enemy* will be something unexpected. like cheifgrunt!
