Personally, I don't even think of "finishing" my island anymore. I had that mentality at first but I realized it REALLY limited the game for me. I mean, once I was "finished", then what...? I'd be SO bored. And what if a villager moved in who didn't "fit" with my finished island? I prefer thinking of my island as dynamic- it's always changing and being "improved". The carnival area I have now could easily be converted to a neighborhood. My farmer's market could easily be a fall festival (which it 100% WILL be come spooky season

). It all depends on the seasons and my mood!
That being said, I'll definitely be tidying up! I need to figure out something to do with my third top tier cliff... Part of it is a lookout over the lighthouse, but now that I've moved my haunted house, IDK what else to put there

I'd LIKE to eventually put a Cafe, but we'll see. I've got time, though, since I'm currently TTing back in Spring, and I'd like to come back to Summer first.
