So, a thought about the progression mechanics, and the ever-present Animal Crossing villain: Tom Nook, Debt Collector.
Early on it's mentioned that you can pay off your holiday package with NookMiles, and early on in this thread people seemed to be wondering if that had replaced the usual debt mechanics. However, then later, we do get the reveal that you can upgrade to a house (and then further to larger houses) in very much the traditional manner using Bells.
The latter mechanics are already very much familiar with us, but I'm very curious about the structure behind "pay off your package using NookMiles". I'm wondering if progression on that front is what leads to the new businesses and buildings arriving, or if possibly the house progression is gated behind the package payment progression, so you have to engage with a bunch of activities before you can delve into the full-on financial nightmare.
