A few months back my wife and I bought a house. Since then we've done some rearranging, and now almost every room has become a game room.
Some pics of the front room.

The family room has a 50'' Hitachi plasma with a Samsung 5.1 system. Most of my current gen gaming is done in here, and I've got a few more arcade cabinets in the room as well.
Lastly, I set up a man-cave in the basement with a 32'' Sony Trinitron for all of my old-school gaming needs. So far it's coming along pretty nicely. I currently have a region modded Playstation, Saturn, Neo Geo, Genesis, Dreamcast, Super NES, Jaguar, Turbografx 16, and NES hooked up to the TV, with plenty more systems packed away in boxes until I get some more shelving for that room.
