No way, the controls are very smooth, on par with COD4 I'd say. Admittedly the scenery doesn't change a great deal, war torn cityscape, but it looks beautiful. As for the story line, it is equal to all other FPS games (except a select few) bad guys, you good guy, you kill bad guy, everybody happy, just the same as all the other FPS games out there that people love. As for the shortness I don't know, I've not completed it yet, I only get to play a couple of hours every now and then.
I actually like the standard green sight machine gun, I can't remember what it's called. I think it's up there with the best of the FPS games. This is definitely one of, if not the best pure FPS game produced on any platform. But I suppose it's like anything you either like it or you don't, for instance I cannot see what people like about the Halo series but loads of people love it so.
Lets face it though pure FPS games have just about had their day, they've done just about everything and re-done it that many times that not much seems new any more. It's either WWII fighting the Nazis, modern day fighting some Eastern European/Asian terrorist or it's SCI-FI where you're a space marine fighting some futuristic Hitler'esque evil bloke.
