As for consoles, I play mostly Vectrex, followed by my 3DO..
As for retro, it's been (recently) almost all Amiga, with some Vic-20...
As for PC, I've been toying with OnLive and played (badly) Unreal Tournament and Trine on it recently.
Last game I played through was Prey.
Before that, a lot of Neverwinter Nights.
(Prey and NWN were native Linux versions)
