He means at the same time, also do have many islands, but can only load 1 at timeI'm just guessing JKSV and NHSE. I myself have at least 10 islands, all different setups, rivers, airport color, ect. If they had a dream save for example, could just load up one of my own saves, and import all the 4 tabs, walla, different island, same player. Then just restore whichever island you'd want for the day in JKSV.
