You get to create your own weapons- that much is obvious. But the gameplay is really fluid and the effects are really great. For example, as you get shot, you can see yourself dismembered in all sorts of gory way... And still walk around trying to kill people. I really like that. There are plenty of gamemodes and loadout variations and you really have to try them out to get a feel for the game. I have been playing it a lot and now im horrible at TF2. Haha. Because its 3rd person.
