Heh, I remember Hexen as well... Used to have that and Doom hidden on my old school's network when I was in the 6th form.
And for me, retro is pre-consoles. So I still have my Amiga 500 hooked up in the spare room. It contains such delights as Dungeon Master, XCom UFO Enemy Unknown, Cadaver, Speedball 2, Heimdall, Lure of the Temptress, Magic Pockets, Chaos Engine, Rainbow Islands, Gods, Ishar, Simon the Sorcerer, Secret of Monkey Island, Eye of the Beholder, Ultima V, Populous 2...
Having said this, I do still have all my old consoles and games too, I've never sold on or traded in a single one. What if I wanted to play them again? And I do. All the Final Fantasy series gets trotted out regularly, as does Wild Arms or Xenogears. Yeah, I'm an RPG kind of gal.
Oh, and I also found and download Secret of Mana for my iPad. That's all kinds of awesome.
