It's an Integrated attribute for Animal Crossing New Horizons: One single save match per Switch. If anybody in your family would like to Animal Crossing Items do their own island and revel in the Island President therapy, well, they will need to obtain a completely new Switch system and a whole new Animal Crossing game.
Otherwise, all of non-first profile to start a match in ACNH are second class citizens living in someone's island and are actively barred from progressing the game or taking any meaningful decisions in its own development.
You'd be astonished how many ACNH sales are actually only people purchasing another copy so they can have a second island on another Switch and play with them both at the exact same time (a few people use the secondary island for storage, or just to become creative in a way they aren't on the main island).
Trading things or visiting a different island to drop or pick up things can only occur when both players are online, so yes, you want two copies of the game on two distinct systems running at the same moment.
Prometheus is just another personal favorite, but I feel like he'd be about Zag's side, he sided against the gods over the titans, backing the winning group, and with people over the gods, once again the winning team, seeing as Zag is destined to triumph, I believe he had back us, and he's not the biggest fan of the gods since they punished him for gifting flame to man.
Gaia is an obvious one, seeing as we're desperately trying to escape the underworld and reach earth, Gaia. .
I did exactly the same as you, bought it a few months back available too lol because I simply kept seeing such positive things about it. Definitely worth every single penny and I'm even considering purchasing the physical release simply to have.
It came out the very night I lost my job to Covid. I spent a good month placing nearly 100 hours to Animal Crossing while I was unemployed, then just stopped completely and have not had any need to go back to it almost a year afterwards.
I mean, the true issue is that the game does not have a lot to offer you.
I'm on the boat that believes this team genuinely updates the game for free because they couldn't get everything they wanted done by launch date. I think other games/publishers may be predatory, such as buy Animal Crossing New Horizons Items EA, when they provide dlc before the matches are launched, in addition to opportunities to microtransactions.
