In my double garage, I have the following machines set up.

Star Trek Next Gen , Batman Forever, Royal Rumble, Dirty Hary, X Files, Starship Troopers, Viper Night Drivin, Popeye, Fishtales, Star Wars Trilogy,
Last Action Hero, Revenge from Mars, Waterworld, Frankenstein, Tales from the Crypt, and 1 or 2 more I cant remember.  I have another loungeroom with another 18 or 20 machines in it and when the machines are all fired up, it looks the goods in there as well.

I only turn the lights on for the machines and nothing else. The soft glow is just awesome and the lighting of nothing but the machines looks terriffic.
I hate lights on when the room looks so good with nothing on but the machines. Its good just to sit there and look around at all the dotmatrix displays doing all there different things. Also, the attract modes are turned on for all machines so at random, various pinnys will just burst out with audio and its really cool to listen to.  The atmosphere of a gamesroom looks the best with it being lit like a camp fire glow.

Just add alot of fine bourban, cold coke and ice, play a few games and just sit back and admire the artwork and the fine design work various pinball legends have designed and invented for this fine hobby. Can it get any better (the nice glow of a pinball machine) for us dedicated pinheads ?, probably not.lol
