I think the idea of Play! was solid. Giving younger and older guests an indoor area with lots of activities to do while the 12-40 somethings are riding the coasters and thrill rides. Mission Space has a small playground and used to have a pretty big game for adults to play, but I'm pretty sure they gutted the latter. They definitely need a little bit more than that imo. It'd make that side of the park feel a lot more well-rounded.
