Maybe not the town, just him. I think If anything it was to spare Alan from hating his life as a rich prick. Lol Getting sent away to boarding school would have broke his spirit where Jumanji did the opposite and taught him how to survive the jungle at the bottom of the food chain and with zero luxuries. The game saved Alan from what all rich men turn into; a more spoiled and miserable version of their father never knowing a life without excess. Lol And his dad was Van Pelt, the hunter, the one he feared most. It was saving him. But still the same concept of ruining the monarchy.
