I have a hard time with this one. I'd like to say that I like 4 the best, as it is one of my favorite games of all time. As I think about it however, I realize I have beaten the first metal gear solid game WAY more than 4 (considering it is way shorter) and I think I like the story in the first solid the best.
Metal Gear Solid 2 is batshit insane and borderline incomprehensible, But I still love it. 3 kinda pisses me off because even with the new camera in subsistance I find myself getting seen a lot. I also don't really care for jungle environments but it grew on me (great bosses too). What do you guys think?
