This game is just a masterpiece. It took stealth to a whole new level. But, the main thing that it'll be remembered for was its innovativeness. This game was one of the first with an actual deep story. Every supporting character had a unique history and contributed to the game as a whole. The music that was composed for this game didn't fall short of pushing the games story and feel forward, along with the intense cut-scenes. Though the game by now looks ugly, the controls and experience are as solid as ever.
Reminded me of playing G.I. Joe when I was a kid in the 80's. Sucked you in like a good movie, kept you interested with the great gameplay. Snake? What happened? Snake? Snake?! SNAAAAKKKEEE!!!
