First off I'm not sure why so many people dislike this game. I think it's one of the best FPS's I've ever played. So I gave it a 10.
Good story line
good weapon selection
good side missions
The enemies don't just stand there, they charge and combat roll and take cover. Great AI.
CONS: Can't think of any that are worth writing down since they are so minor.
I am still playing this game and it's very hard for me to put it down at times. It's been a long time since I played a FPS like that. MW3 was awesome but I'm more into the SCIFI kind of games and this one rocks. I will be looking for more titles from id and Bathesda. Two thumbs up from me.
