This has felt like the perfect combination to me for a few months

I opted for a pc, but I guess a rasperry pi should do the trick provided you can get one that doesn’t cost an arm (see what I did there?) and you can slap a disk on it, SD cards wear off quickly. A mini-pc/nuc or similar would pack more punch, I don’t know about prices compared to a rpi.

Once you have gnu/linux installed you can do whatever you want.

About remote control kde connect does wonders if you choose to use kde plasma as desktop environment, I heard a port for gnome exists that works well though.

Some beat them up: tmnt, streets of rage 4

Also since you did not mention playing remotely or not (although there are ways around that: parsec, steam remote play together…) almost any couch coop game: overcooked, moving out, unrailed…

Edit: all of those I cited have a online multiplayer mode I think, for overcooked the AYCE edition contains all of the first edition content but brings online MP amongst other things
