#08 - Metal Gear Solid (Kudos to Wright for guessing this)
I replayed Metal Gear Solid on my Vita recently and it made me realise what a timeless game this is. Really, aside from some slightly-dated-by-modern-standards controls and Snake's complete lack of eyes, everything else about this game is still a masterpiece of the highest order.
Featuring one of the more ridiculous yet actually comprehensible plots I've played in a game, mixed in with some fantastic characters (even the villains were fleshed out well in this game - I felt truly sorry after killing Sniper Wolf) and great stealth action gameplay; it remains one of my favourite games to this day. The bosses are just endlessly creative and some of them (bike chase with Liquid) actually made me feel like I was in an action movie which was just absurd at the time. I can see why Kojima went with the direction he did for future games.
All in all, fantastic. And since I brought it up... *sniff*:
