1) Family sharing works on all platforms except Epic, which doesn't support it.
2) Only the primary account receives bonus items, such as cosmetics. Additional accounts get access to the expansion but do not receive these extras.
3) Only the primary account receives the early adopter bonus. Secondary accounts only get access to the game.
4) Expansion 2 is limited to the platform it's purchased on, meaning players must buy the expansion separately for each platform they want to access it from. For instance, if a player with linked Mac and Nintendo Switch™ accounts buys The Storybook Vale on their Mac, they won't be able to access the new Village in The Storybook Vale when logging in on their Nintendo Switch. However, this only affects access to the expansion; items and missions remain accessible across platforms.
5) The storylines of Expansion 1 and 2 are not related and neither expansion is required to play the other one.
Some characters from Expansion 1 will be present in Expansion 2 but only if a user already has those characters. Otherwise, these characters will be swapped for base game Villagers.
