I love the overall aesthetic of the gameboy (my first system as a child).  I love SNES games (esp. Earthbound, Chronotrigger, and FFVI).  I love the 2d Castlevania games.  All I really play on the computer is Dawn of War.  As far as newer systems: Silent Hill, Metal Gear, FFVII, and Shadow of the Colossus.  I rarely have time to play games anymore though.
