I know what you mean about those flat head screws!! 

I understand the passion for these games, as I have it too. Although I did appreciate my System 3 Stargate, and miss it too now. That game holds it own with all but the best B/W DMD's.

Never had an EM, but have a couple of System 1's and love them - they were still EM in style until things went System 80. Love my Black Hole and Spirit, these are fascinating games and extremely good players. As Nino said, the guides have made these games way more accessible. Both games have all original boards but with the mods are super reliable.

Big  for Gottlieb!!!
