I LOVED Space:1999 when I was a kid. I still love the gear and uniforms and such (mostly from memory - been awhile since I've seen it). Even looking back after all this time, I think the tech holds up amazing well - certainly the most "realistic" looking ships and gear that I can recall. And I'm pissed that we don't have a moonbase NOW, much less back in 1999.
Also - actually noticed when the date for the moon being flung out of oribt came around in Real Life (tm).
Geek.
Actually, I think I have the series on DVD in a box somewhere, now that you mention it...
I don't know much about the "Starblazers Adventures" game, but it sounds like S:1999 would be a perfect setting for it.
