Everyone plays a little differently, but I find that the best way to get things rolling is...
Before playing...
- Have an idea of what you want to do with your town. There's 4(?) themes you can choose as far as PWP: modern, natural/rustic, fantasy, zen. Go through the list of PWPs online and decide on the ones that look like they would be cool to build your town around.
After the first week or 2...
- You presumably have 9 villagers. Get all 10 for your complete population (you can also trade, give TBT, or IGBs to people here for dreamies if you don't have amiibo). You can either cheat, use the reset trick, or just live with the random plots that they do. Either way, once they're all settled in, you can start small by doing some basic landscaping.
- If the QR machine from Mable is available (talk to her for 10 days), scan a path set that's simple and fits your planned theme. You don't need to do anything elaborate yet. You can just start making a path that connects villager homes to the town tree, retail, the train, etc.
- Before you start laying down PWPs (a few of which are permanent: campsite, reset center, cafe, police station) or anything else, if you have fruit trees left after your move ins, then collect from all of them (including perfect) and save them. Don't sell these. Any future villagers and PWPs (if you don't have dreamies) can leave you without trees that grow crops.
- Go to Nookling's everyday and buy furniture - even if you never use it. Same with the Able Sisters. The items you collect now will go towards the catalog and most things can be bought again. The point is, you want as many options as possible when you actually start getting your house decorated. Another way to get furniture is to buy items off of campers (once you have the campsite - not Harvey's). Nookling's stores limit you to what's in stock for that particular day. Campers can give you infinite items where the only restriction is how many Bells you're willing to part with (some items you buy will be cheaper, some will be 2-3 times more expensive than Nookling's/Retail).
3 weeks into a month and beyond...
- Start building up your house. At the very least, get it to 8x8.
- Do initiatives on your ID card. You get 2 goals (red) that last the day and 2 (blue) that last the week. Get MEOW coupons, and you can get items from HHD, items usually restricted to holidays, etc. from Harvey's camp and the RV's that show up. You can also trade these coupons in for Bells.
- Talk to your villagers. Do them favors (I would ignore fish/bug/trades if you want their furniture untouched).
- Build your wealth by going to the island and catching beetles and sharks.
- Build your museum. Donate bugs, fish, crustaceans, fossils, genuine art. Get the second floor.
- Get all your locations on main street (Katrina, Dream Suite, Club LOL, Shampoodle, Kicks, Nookling Emporium with Gracie).
- Get all PWPs overtime and start building them. I do the permanent ones first - in out of the way locations - then the more scenic ones.
- You can start getting fancy with landscaping.
Remember...
Take everything a day at a time and keep your goals small. AC is supposed to be relaxing, not a chore, obligation, or overwhelming.
