Not only did it not take advantage of the system all that much, but it had framerate issues to boot. The only reason I can sort of see why they put it on PS3 was because of the whole "We got here first!" and "Wii already has 3 other games like that and more to come. Too much competition!" Their FPS mode might be potentially the other reason, in no way does it even come close to MP3 or MoH2 in terms of fluid control and aiming, the damn gun has two analog sticks on it for freaks sake. The rest of the controls are in no way decently streamlined well enough to work together either. Reload with a button? Aim with a stick? That's so last generation!
I take that back, last generation? More like last era.
