I strongly recommend Rusty Lake Hotel, but only if you are into Point and Clicks, Puzzles or Surrealism. PC version works reasonably well, runs in Flash

Metal Gear Rising is one of the best spectacle fighters available on PC. This game will keep you hooked untill the end, with nonstop camp and action

David Szymanski has managed to make a fairly interesting game here, dispite some major flaws. If you have a spare $2, its worth checking out.

A very enjoyable and unique, if not somewhat janky, sandbox RPG. Improves on the original in every way! (old video)

Gunpoint is an interesting 2D side scrolling stealth game, which plays more like a puzzle game than simmilar games. Has a tongue in cheek noire flavour!

Hotline Miami is a unique 2D shooting game that is in a genre of its own. Fast paced and lethal combat is the name of the game. (Older Video)

Receiver is an interesting proof of concept, showing that realistic weapon behaviours can be engaging in an FPS

FTL is an excellent 2D spaceship exploration game, centred around escaping ever-present rebel pursuers in order to deliver vital info to the Federation!
