Nook Miles+ and Binge-Playing
Animal Crossing games have always had a soft limit on how much you could do in a single day. Fossils only show up once a day, trees can only be shaken once a day, flowers can only be watered once a day, and so on - plus many event triggers (such as house expansions) have built-in overnight delays, so even once you hit one of these goals you can’t move forward past it until the next day.
You always could keep playing, catching more bugs and fish and picking up more shells, but at that point you’re mostly farming Bells. It’s an option, but it’s not where the game’s best experiences lie and I don’t think it’s what the designers really want the player to do. It’s possible because none of the mechanics forbid it but they don’t particularly reward or encourage it either.
Because of this, I’ve always gotten the impression that Animal Crossing wants to be played a little every day. You can choose to binge it and try to play as efficiently as possible and rush the various objectives, but the game neither encourages nor supports this approach. It’s designed to be less fun for players who come at it like that. It’s designed to slow you down. It wants to be a Zen garden, not a checklist.
New Horizons adds a fascinating feature that runs somewhat counter to this - the Nook Miles+ program that comes pretty early in the story progression. At all times, you have five mini-quests active that reward Nook Miles (a secondary currency alongside Bells) when completed and instantly replace themselves with another objective. These are things like catching five bugs (or five fish, or one specific bug or fish), spending Bells, selling items, crafting items, tending flowers, and so on - things that are very much in the “things you were probably going to do anyway” vein and often things that also earn you Bells along the way.
What this means is that even once you’ve done all the significant things you can do in a given day, you constantly have a short checklist of directed activities. You always have goals to accomplish for rewards. In some ways, it feels like a very non-Animal Crossing concession to players who want to binge and clear checklists. You can keep playing and knocking out more and more goals.
But at least in the early game, it seems to be less rewarding than it first appears. At the very beginning, Nook Miles are incredibly valuable - they’re how you repay your first debt and progress the game to unlock more mechanics and activities, and they can be spent on some absolutely vital purchases like an increase to your inventory size and a tool quick-select ring. Once you get through those things, though, there’s much less to do with your miles, at least in the early game. They still have some use and value, but at this point I have tens of thousands of miles just sitting around so it’s hard to find the Nook Miles+ objectives particularly compelling. I’m back to feeling like the game wants me to put it down until tomorrow.
