I know this is an old thread, but i always enjoy looking at everyone's gameroom pics. i finally got around to taking a few pics of my family room/game room. it isn't nearly as awesome as most of them, but it is in my main living area of my house, so i can't go all out like some of you. besides, i figured if i posted mine, then maybe someone else might not be so intimidated by all of the amazing rooms in this thread...
here is the back half of the room, with the cabinets

here is my 4player showcase MAME cabinet

this is my vetical classics cabinet

here is my dartboard and candy dispensor (Reese's Pieces - FTW!!)

here is my the other half of the room:
This is my 102" projection setup for console gaming and watching movies

here is my component rack: PC to left of rack Athlon 64 x2, 4gb ram, 1.5tb storage, etc.
Psyclone Component video switchbox, DirecTV HD receiver, Playstation 2, Halo green XBOX..modded with 250gb hd for emulators and XBMC
Onkyo Receiver, Wii + 5 port HDMI switchbox, Playstation 3, Xbox 360

here is my rack for my Guitar Hero / Rock Band guitars:

here are my console games (currently connected systems only) all of my older consoles/games are in boxes in the basement, since i have the emulators on my xbox. Up high so my 2 year old doesn't get them

there is a couch in the middle of the room, i was just standing in front of it when i took all the pics. right behind the couch is a tiny recliner and a 26" tv for the kids to use. i dind't take pics because it is lame.
we have been in this house for about 2 years now, my wife is unsure if she wants to stay here, or look for another place in a few years or so. if we move, a basement gameroom is on the must have list, if we stay here, we have made plans to build a gameroom on to the back of the house...so maybe someday i'll have an awesome game room like some of you, but for now, this will have to do.
