Not sure my kids really care about best LCD theme to be honest. My daughter only plays when she has friends over and usually only plays a game or two before going back to play with slime and fidget toys. My son will play if someone is with him and encouraging him to play. I could never see my kids just turning on a machine by themselves to enjoy a game by themselves.(maybe someday?) I quit caring about what game the "family" might like and started focusing on what themes/games I like instead. As much as I want it to be a family hobby-it is not. My best purchase for the kids was a Game Gate multi-arcade mame machine with pretty much every arcade game ever made on it. The kids play it almost daily, and if not the multi-cade they play Nintendo Switch. Just bought the Mario race wheel set up and the kids are enjoying it tremendously.
