These days grandpa developers (and many grandpas in general) grew up playing rogue/roguelikes and watching plinko played on TV while being reminded to help control the pet population by having their pets spayed or neutered. I don't know how popular pachinko is outside of japan though. All the pachinko video games I've played to date were old and intended for a Japanese audience.
My favorite is pachincremental but I have an unnatural affinity for those games. Number go up.
Someone called doom and quake boomer-shooters and that's funny to me.
This comment introduced me to pachinkremental. Thank you / goddamn you.
You're welcome and thank you ;-)
pachincremental really was a fun diversion! Too short though, so now I'm giving Universal Paperclips another go (never did finish it)
