That is what I was thinking. The parts aren't really any different to what is available today meaning minimal R&D on new toys and less cost overall you'd think. The above mentioned titles prove that a machine doesn't have to have a licensed theme to be a success. Any sort of sci-fi, futuristic, spacey sort of theme always seemed to work well.
I am not 100% sure if making every machine family friendly is the way to go, afterall who buys these machines.....us old farts who have a connection to these machines with some spare cash here and there. The themes didn't affect us when we were kids or no more than what video games are doing to kids these days.
This of course is just a personal wish but I would love to see a modern version of an early SS style machine brought to life. Not a re-make but a new title.
