I wish somebody had as a passion project or company to build Space Cadet into a real physical pinball table.
Many people have thought about this, IIRC it's not physically possible to build because there is a lane that goes under a bumper (which in real life they extend down quite a bit) https://files.catbox.moe/pnaeri.png
I suggested this to a Stern employee 21 years ago, which obviously went nowhere. Back then they were trying to do a Halo machine, which also went nowhere.
There have been a few attempts at this. I think the most well-known one is probably this one [1].
While we’re at it, I’d love to see a physical version of the seseame street pinbal table [2], though that one might be a bit more ambitious. :)
