I've never played one so I can't comment about game play (have only seen some crappy YouTube videos), but everyone makes the game play sound as if it plays like Hercules or something... It can't possibly be that bad, is it??
If they did 100 or less of them like Nate was conjecturing, I think that would be just the right amount. Enough games to honor and see out Python's vision, but still rare enough to be exciting when you see one, especially if you know the story and history of the game's designer.
As far as footprint... Yes, I'm sure it's a beast to move from an operator's stand point back in the day. But once it's where it's going to go (in a collector's walk-out basement, garage, etc.), it's not deeper than a pinball machine and doesn't look any wider than my Space Invaders cabinet and back box.
It'll be way out of MY personal price range, but I wish the project well and hope they are successful!
