Video games at CES are weird. Let's just get that out of the way. Unlike at E3, which focuses exclusively on games, video games at CES are more like a sideshow focused on hardware -- a cute thing that middle-aged men might check out en route to a VERY IMPORTANT MEETING.
And that's why so much of CES gaming is retro focused, so let's start there.
Because CES is absolutely crawling with old men in ill-fitting suits, the show floor is packed with pinball machines for folks trying to relive the '80s. I want to talk crap about this Stranger Things spin-off, but look -- it's amazing! The game is fun, the tie-in makes complete sense given that the show is set in the '80s and focuses on kids who spend their time in arcades.
Best of all, it's an actual, proper pinball machine, unlike the following abominations...
I saw a lot of terrible, "virtual" pinball machines. These are essentially screens embedded in a box shaped like a pinball machine. They do a great job of removing everything interesting about pinball machines: the tactile feeling of bouncing weighty metal balls off metal components.
It's called VRLCO and it's a VR system for arcades that players can use without any assistance. If you've ever used VR in arcades, you know they usually require assistance to get set up. These ones apparently don't. They come with a bunch of interesting games preinstalled.
Also they apparently self-clean. That's probably the most important part.
