My question is if we can make the Pi turn on "Game Mode" on our TV's with CEC or ARC? (then off when we're done playing it?)

I'm not sure if that can be done dynamically, but you can set 'game mode' via config.txt - https://retropie.org.uk/docs/Input-Lag/#set-tv-to-game-mode

Thanks for the link! Tried that on my Zero 2 W and RP4 and didn't work so don't know if that's an issue with the software or whatever.. or I also researched my TCL TV which has a history of firmware updates messing with some CEC protocols... so who knows. I would test it on another flatscreen I have but that's a TCL brand too ;)
