Yeah, it sounds great, and actually @mcFunkyPants was talking about a similar idea on Twitter https://twitter.com/McFunkypants/status/1250152067533950977?s=19

There's some caveats, though: each game is owned by their respective creators, so while you can build an arcade cabinet with the games for your own entertainment, you cannot sell them or make money off of them.
