Since there is so much MGS talk I just wanted to chip in
Snake Eater is the best MGS game and there is no debating it.
Best story
Best Healing system
Best music
Best intro (even better than MGS2)
Best villain (Volgin)
Best setting
And most importantly best boss fights. The Cobra unit was the fucking shit.
All the fights were different and unique. The Sorrow boss fight was probably the most creative boss fight in any video game. I wish Kojima brings MGS3 to Steam. It is a timeless classic and probably the best console game ever. Its the one MGS game I wish I had in my Steam library. The rest are great as well but none of them are in the same league as Snake Eater.
