What you forgot to say about Fear is that it is just ten hours of that same Matrix lobby scene over and over again, without even the setting changing.
I guess the gunplay of Fear is ok, but everything surrounding it is well....
Didn't play 2 or 3, but I have them.
I don't know what the best playing FPS is. I feel like Half Life 2 is the complete package. It's gunplay is pretty great, oh it dosen't have slow down and papers flying all over the place like Fear does. But when I played it I also did'nt think it was the most amazing thing ever. Parts of it are really boring actually. Episode 2 was good though.
Bulletstorm was great if only because I felt the desire to try do specific things with the guns.
Perfect Dark is one of my favorite games, but I don't think I could handle it today.
