I saw an ad for this Sandbox.game (which looks fun) and I couldn't help but notice a clip where people are chasing each other with pies in what looks like a big pie throwing booth.
The full ad is here: https://register.sandbox.game/alpha3?utm_source=adwords&utm_campaign=18161551421&gsc=1&utm_medium=_5651876&gclid=CjwKCAjwg5uZBhATEiwAhhRLHtKVt9myr2gc8R-4L7uqDl94THQBUsaYB5ONDeoHbzuYZ3bhvhbPGRoCXvEQAvD_BwE&wbraid=&gsid=1ed37bc3083a691a8272ba0126ee03cd
I remember people setting up a pie throwing booth in Second Life. Maybe this will be better?
