Animal Crossing New Horizons should allow for multiple islands per console.  The files are saved in the console's memory, not on the cartridge.  The game cost full price at $60, not $40 like a DS.  Finally, a new Switch console costs between $200 and $400.  We should not need to pay that much to create new islands in one household. 

Like many others, my family shares a single switch.  I started my island first before realizing it would affect all of the profiles on the Switch.  Any triple-A title should allow for multiple, separate saves.  The Nintendo Switch is not a personal console like the Nintendo DS family; it is a family console.  If my partner wants to create her own island separate from mine, she should be able to have the island resident experience.  Same goes for kids!  This is disgraceful on Nintendo's part. 

At the start of the game, players should be able to choose if they want to move to an already-created island, or start their own.  Then, players should be able to buy new islands with bells or Nook miles.  The idea of the game is an island getaway, and to expand your homestead.  Add additional island expansion, and allow profiles to create their own, separate islands so we can all have the island representative experience.
