I enjoyed Halo even though it shared the "Bungie lag" like this game, I loved messing around in the forge and appreciated the theatre mode But I've also gamed hard on Gears of War 1,2&3, Operation Flashpoint Dragon Rising, Battlefield BC1&2, BF3, BF4, Crysis 2&3, TC Advanced Warfighter 1&2, TC rainbow six Vegas 1&2, TC Ghost Recon future soldier,Alien vs Predator, Age of Empires/mythology And more.
