Emulators, 'nough said.
More seriously, not a lot TBH. Nothing that is on a console and not a PC really interests me, and same for handhelds. All the RTS and 4X I could ever want are on the PC, and I have enough RPGs that even the loads of others the PC has don't interest me that much, whilst I only enjoy the older FPS like Halo CE, or Quake 3, or BF2, and will only buy the newer ones if they have shiny graphics for me to make Desktop Wallpapers for myself with.
