DK Jr looks awesome!!!
I have played similar games to these but not the actual tabletops. I recently bought an old Galaga handheld that plays diagonally from the bottom left.
These games are so much fun! I have a hard time getting a very high score without getting frustrated, but I'm always coming back for more..
ps. I did have some sort of early tabletop video game system that I think took cartridges but had a game or two built in... I couldn't for the life of my remember what it was.
It was black, and I think the carts went in under the "screen". THat was a yardsale find when I was VERY young. Early early nineties.
