My game room is pretty tame compared to some of these, but I'm really proud of it. It was an unfinished basement when we bought the house a year ago, and we spent about eight months putting up the walls and ceiling ourselves. This video was recorded rather hastily once everything was finished so I could show the new room off to my friends and family. I know it's not technically "pictures" as requested, but it's all I've got handy.

3 PCB that we can swap into the DK Jr cabinet, so we have a little variety there. Replacing the original wiring harness with a DK3-friendly Edge Connector one was a fun challenge since it was the first real work I've done on an arcade machine. Also, the serial number on our DK Jr machine is 20. I don't really know if that makes it special or not, but I've always found it entertaining.
Hopefully some time soon we'll be able to add something new to the lineup (we've been looking at pinball machines recently, but getting one squeezed into the room layout will be a challenge). In the mean time, my wife and I play a lot of pool and challenge each other's high scores on the three games we do have. We get a lot of good use out of this room.
