Remember kiddies, this is my opinion, not fact. Halo CE: 5 Halo 2: 8 Halo 3(360): 7 Halo 3(dedicated servers[after the tornado of crashes in MCC]): 9.9 Halo Reach(Pre-Update): 7 Halo Reach(Post-Update): 8.5 Halo 4: 4 Halo 2A: 6.5 Halo 5(Beta): 5 Halo 5(Launch): 7 Halo 5 would be a solid 8 if it hadn't been for the mass amount of aimbot-tier utility weapons and the lack of understanding from 343i of 'less is more' when it comes to weapons and abilities. Post-patch Reach and Halo 3(when the dedicated servers are actually working) are what I find to be the sweatiest of all games.
