After finally getting around to playing Deus Ex: Human Revolution (awesome graphics and gameplay, awful everything else) I've started to miss my old Tenchu and Metal Gear Solid days. Unfortunately, as I'll never own a PS3, and my 360 is baked (thanks to a 2 year old) I can't play either of those.

I've got a PC that's pretty powerful though.

Anyone have any suggestions for a PC game that's similar to Deus Ex: Human Revolution, Metal Gear Solid or Tenchu? I'm fiending here.

The Thief series? First-person fantasy sneakers.

The, you know, first Deus Ex?

also how can you not love a game where you can just smash a hooker right across the face
