Quoted from Crile1:I know you said Stern, but I would recommend Hot Wheels. I think that would be great for younger kids. My teenage kids love it. Also, if in your price range, consider P3 multimorphic. Heist and Cosmic Cart are great games for kids and adults. Mini game ROCs and Barnyard are great for kids and add variety without swapping playfields. Plus a new game is only $2500 to add.
Team Play is also available on the platform. It's basically Co-op, but you can do mixed matches where the kids all team up on one profile playing against Dad, or a mom and dad team. It's all built into the P3 Profile system which also allows the players to save their progress through the game and restart games later picking up where they left off. Great for them working their way through a game, or setting up practice scenarios, like the various jewel heists in Heist. Plus you can always switch up gameplay to other games quickly. ROCs is basically asteroids in pinball form.
