Wow, the graphic style on Cooper's 9 is so fun, I want to check this out!
Lightguns games are one of those things which is important to have at home, but they often have a special design in the cabinet structure which makes them fun to find in the wild while you still can. I think the game I'm thinking of has been dumped, but I saw a lightgun game on a cruise ship i'd never seen before; SEGA Golden Gun. It's apparently only about a decade old, made by some Chinese arm of SEGA, and it had some cool big shiny guns on the cab.
Maybe once we have gun-sensing technology back for modern screens, we'll get some choices to take home a bit of the style of the physical units themselves.
