Poptropica Legacy is a fanmade remaster that allows playing classic Poptropica islands & ad experiences both online and offline. It includes both the AS2 version - the first one from 2007, including the 37 original island quests - AND the AS3 version - also known as the SUI version within the community, including 14 island quests of it’s own plus Poptropica: Realms - with more than a few major changes/improvements.
