MGS 2 was one of those games I watched, rather than played myself. About 3/4 of the way through it suddenly becomes the Greatest Video Game Ever Made. You should enjoy it a lot.
I agree that it's a game better watched than played. The whole thing about it becoming one of the Greatest video games ever made.... I could stand to live without the visual they gave us of Raiden when he was running through ******* Gear...
