If you haven't already played this, just do it. It's one of the few games out there that's worthy of being called perfect as far as what it set out to accomplish.

This is what I've always wanted from a stealth game. The amount of pure choice they allow the player to have in this is incredible, and every single step of the game is thoroughly thought through.

The choices aren't forced into a single line of good VS evil either -- they are purely a means to an end in progressing through the game. Every element is intuitive and engaging, and I've never played a game where I've had so much fun sneaking through vents and tazing guards.

Play this. Do it now and we can talk about how awesome it is later.

A criminally-beautiful game with one of the best soundtracks to come along in games since the 90s. Even if it starts out slow, the story is very poignant and haunting. I can't think of a better way to spend 15 dollars.
