TF2 did for a while then they started adding hats and other stupid shit.
CoD was cool, specifically the servers that had no lame ass cross hair. I have been anti cross hair that long. running and gunning, spraying your gay all over the place just doesnt do it for me. People aiming, kneeling and getting a head shot from the hip is just beyond stupid. Giving players things like a Aimpoint and still having cross hairs just proves how lame it is.
The trailer doesnt show a whole lot. Pretty graphics, doesnt show the lame radar BS they had in the previous game. Likely has more lame ass levels, perks, achievements to unlock stuff that should have been in the game for you to use in the first place. Again, basically making the game appear deeper than it is.
Still waiting on a FPS that isnt completely consolidated. Maybe Planetside 2 will be that game?
