I would stick with the 60 in 1. You dont want people spending 30 minutes looking for a game on a eleventy billion and 1 game set up. Technically all the multicades are illegal. Doesn't matter if it's at home or on location. They are emulating Roms that, if you dont own the original board, are illegal to have. Nobody says anything because most of properties on those boards are just lost. Aside from galaga and pacman.
When these boards first came out they were everywhere. I believe someone representing namco showed up and told the auction in Tennessee or North Carolina (same people) they couldn't sell them thru the auction any more. They let everyone pull their games and put them back on their trucks. After a couple years they started selling them again and no one cares now.
I think you are okay running one. I also been told more adults play the multicade then kids. If you dont have some already I would get a crane, stacker, or other self redemption game.
