When I was in elementary school, my math class spent a good amount of time playing Roller Coaster Tycoon in small groups. I can't remember exactly how it worked, but I think we rotated who got to drive, while two or three other kids watched and gave advice. While a lot of adults have fun pushing the boundaries of Roller Coaster Tycoon (e.g. designing roller coasters that smash into each other), we were very serious about it! The goal was to make a truly profitable park, and I remember having conversations about optimal ride and souvenir pricing, revenue per building, etc. (with our very limited vocabulary). I think games need to be fun first and educational second to have any chance. We didn't realize we were learning while playing RCT, we were just excited by the challenge and the goal. The means to achieve the goal just happened to be loosely grounded in real world business practices.
