The Anniversary gametypes come closer than any other Halo game, but there is still an entirely different feel.
If they came out with Combat Evolved multiplayer on xbox live, I dont care about graphics or audio upgrades, and just put the multiplayer out, I'd pay for that. I was really disappointed when I found out the anniversary remake didn't actually remake the MP. Its like HEY HERES FREE CAKE! and then you get there and its 1 slice of bread with butter and sugar on it.
