MGS1 was the best, I wish they'd remake it, but they won't because of the Gamecube Twin Snakes remake that was already done... which made it even better. I liked 3 a lot, but I didn't like having to pause every new environment to change my camo to get to a good 80-90%. I thought 4 was outstanding besides the crawling through the radioactive room part for absolutely no reason. Piloting Metal Gear Rex was epic!
