I dumped tons of quarters into Smash TV as a kid. I'd like to own one some day along with another NARC machine, but with limited space they just don't make the cut
Smash TV has an ending. Once you reach the ending there is not much motivation to play it again. I owned one about 14 years ago and I had the pleasuredome roms. The roms don't add much to the game. When I got good enough to finish the game, I got rid of it shortly thereafter.
