Let down?NO WAY!
I have half life2,Call of duty,and most of the other famous FPSs,and this should be up there with them.I only wish atari would have spent a bit more time on it,as it can be a bit dodgey at times,but that does not spoil its fun.
The vehicles are fun to control,including planes,helicopters and even buses if you get a job.Get drunk ,take drugs do anything you can imagine in this 450squarekm of gameplay.I think people do not like it because it demanding.My pc works well enough to run it pretty well,but no matter what the box says you need at least 1gb of RAM,i think i have 1.3 gb or something,well anyway it is worth getting if your pc can take it,atari should have finished it first though.The story is cool and the graphics are smooth.
So if you see it pick it up.
