I love the fact that the enemies move around, it is not really done in many fps games and it should because it's realistic. In real life, enemies would run, duck or hide behind cover. But the aiming in this game is pathetic. It is the game's worst trait, in my opinion. It's the reason I barely play online(or offline for that matter) with this game, the aiming is too hard, and I end up realizing it hardly requires skill, more like luck. And that is not fun to me. I love COD2 online, but of its great aiming, it's all about skill with that game(too bad sniper rifle are the only thing used though). But even King Kong has better aiming than PDZ, and that's ridiculous.
