I enjoyed Unreal 2, despite it being so linear, mostly because it was primarily a fighting game, not a stealthy game, and because it looks so damned sweet. I also had it in the back of my mind that there would have to be a multiplayer addon, which would deal with having to play the thing once through. Finally, U2 is finished in less than 10-12 hours, while SC goes on, and on, and on.
I realize that most people like SC and don't like U2, but I think it's important for me, if I'm going to review Unreal-engine games, to publish what I feel after playing the game, whether it matches up with popular opinion or not. So call me whacked, or lose faith in me, but I like U2 and Postal 2, and I found Splinter Cell boring, stifling and pretty much contrived.
