One of my gripes about Halo 3 is that all the human weapons except for the Rocket Launcher and Spartan Laser just "felt" useless. Even their sound effects sounded like they were
vibrators rather than guns.

And the Brutes were silly. Srs, they went from being awesome primal mindless killers that you really feared in Halo 2 to being basically Elites without energy shields in Halo 3.

A lot of other gripes that I can't be bothered to list here basically culminate in me not liking Halo 3 as much as the first two...
Halo 3 was a good game, just not as good as the first...
