Eh I like the achievements on TF2, but I don't let it affect how I play. It actually feels much better when I play normally and I achieve something. It's easier that way rather than trying to chase after every achievement just for the sake of it.
the mouse wasn't as bad as I thought it would be, but it has no place in a PC GAME. I read somewhere it was intentional so the console and PC versions would feel the same. WTF, one of the reasons I prefer the PC is the control scheme is more precise and easier to control. This is one game I won't be spending my money on.
I knew some Marines who were there. It's quite a story.
