Yeah, it's more "story based" in the sense that you are building an island settlement from scratch. It's comfy same as it always has been, but it's nothing groundbreaking really. Just adopting some of the more common mechanics out there now like crafting. Haven't played enough to see how much content the characters have (the trend has been to get shallower), but the random interactions are pretty neat. I've caught some of them singing or trying to catch bugs and all that.
Pretty lame about the whole 1 island per console thing. Nintendo gets weird about DRM with stuff like this. They could figure it out. The game doesn't take up that much space to save your data. Same thing goes for split screen. It's weird that a second player is stuck following around player 1 if they're on the same system.
Odyssey is really weird with how it distributes the moons. You get one moon for talking to the right NPC or paying coins in the shop and you get one moon for doing some obscure and difficult challenge. I would have made it so there's 2 different kinds of moons - noob ones and pro ones. Then to advance through the levels you need X noob ones and Y pro ones. Then instead of giving you 3 moons for beating the kingdom boss, you get the easiest pro moon. And then you can lock some content behind collecting Z pro moons so if you're up for a challenge instead of 100% you can just ignore the easy gimmicky ones and look for the challenge areas.
