Also jump > no eyes for Snake. Plus the Ninja fight in the original version is stupid. 1/4 HP left and then Ninja goes explosion on you and you perfectly have to time your attacks.
Also the jeep scene with liquid is like 40 min long on the PSX version. Add on top of that how easy Sniper Wolf is cause they forgot to make Nakatas jam on that second fight and the fact that Chaff grenades don't work right on REX... I'll take the Gamecube one anyday. :)
Uh, basically rock and it's derivatives. Some pop, but Rock I'll like whether or not the band sucks sometimes. My favorite rock genres are Heavy Metal (Iron Maiden, Megadeth, etc), Punk Rock (Ramones, Bad Religion, Gob, etc) and well, stuff like Alice Cooper and David Bowie. Queen is another one of my favorites.
