The maps I can agree with. SWAT is now a ranked playlist in Halo 3, but everyone runs around being elites since its harder to hit them in the head compared to Spartans. IMO the Scorpion is very imbalanced, if you don't have one and you happen to walk by someone using a tank, you basically going to die. The AR is actually stronger than the BR, but it is not meant for long range shooting. The lock-on with Rockets was stupid, made it too easy to get kills with them. I prefer Halo 2's story, mainly because the Arbiter's storyline was interesting and the stages looked a lot better than anything in H3 or the 1st Halo.
The original Unreal Tournament and Rainbow Six are better than any Halo...Halo is boring and sterile. Every online shooter gets boring after a while though...I was only playing hardcore search and destroy on COD4 but haven't touched it in forever.
