When I last left the game, I was working on my house HHA rating & really trying to perfect that. Granted, I had about 3 homes in my town I was working on, so it was more difficult to achieve. I also have way too many things just scattered on the ground of my town that I haven’t been able to pick up & clean up yet.
Never fully completing the StreetPass and Dream Suite badges was a bit disappointing. I did as much as I could at the time. While the golden StreetPass badge is theoretically still obtainable (by communicating with 1,000 players... or yourself 1,000 times), I will never be able to achieve the golden badge for the Dream Suite for obvious reasons. Heavy Sleeper will have to be good enough, haha.
I always reset my towns before i can complete everything getting all the pwp's traditionally is difficult and takes a lot of time, but i'm challenging myself to do it, and also finish the museum 100%.
I never finished making my town the way I wanted and it's still covered in items (just like my new horizons island but even worse XD) I also never finished the museum, my catalog (i don't think i did at least), and i never unlocked all the gold tools or got a perfect town, I need to go back and do stuff in that game, and sell all my junk to the nooklings since theres no online anymore to trade with lol, hopefully I'll actually complete my island in new horizons and get all my extra stuff traded so its not a repeat of new leaf XD I'm trying to get tid of all my extra stuff in new horizons now and even have a thread but only one person has bought from me so far, so idk how well that will go, i hate selling stuff to the nooklings when i can trade it online XD i wish I'd gotten rid of all of it when the hype was still big and it was easier, at least my town isn't nearly as bad as my new leaf one was
