People should rate each game individually, these games are made to stand on their own two feet, why see a game with a gun and call it Counter Strike or TF2 or something?, just because a game came out earlier doesn't mean you should compare every new game to it. Obviously there will be similarities because there's only so many game mechanics a game can have, so expect guns *oh my*, running, menus, character classes, teams etc... Don't question it, just accept it.
Brink looks like it is going to be a great game, and quite complex which is something I like in games, I prefer complexity of equipment than simplicity. I hope they make it perfectly balanced so no gun stands out too much that everyone starts using it.., and I can't wait to see what kind of character skins you can design.
