I didn't play Crysis SP all the way through, I got bored frankly. Seemed kinda thrown together. I have to explore everywhere so open area games like crysis make me mental. Halo is able to reign me in and keep me focused on the game so I get a more well put together game when I play games like that. I like games that are linear but feel open like halo and modern warfare. I am pretty sure they are trying to keep the player focused more in C2 and this is very exciting for me. I like the game to feel like an interactive movie. A couple of open games like Fallout 3 and Oblivion worked great though. I think because there were a lot of options for side missions and main quest.
I saw the previews of C2 and it looks very cinematic. Very linear too, so I can't wait.
