i can confirm that pokémon is normal and lets you have multiple switch accounts with multiple saves on one console. which is actually a big improvement, because pokémon never let you have multiple saves on one cartridge, so on older consoles you did have to buy multiple cartridges! (thankfully you could share the console because the save was on the cartridge, not the console)

on switch, animal crossing is the only game i can think of where there’s only one save per console. and even then, i think they added save slots in the latest update

5 years later… meh. better late than never i guess.
