I have from newest to oldest:
1x DMD Stern: Lord of the Rings
1x Pinball 2000: Revenge from Mars <-- newest addition!
1x DMD normal cab: The Shadow
1x DMD widebody: Indiana Jones
(1x DMD widebody: Twilight Zone <-- from my parents, but in my room)
Don't have room for more, but really would like some older games (EM/SS) to join when I'm moving out of the house.
