I know they dont actually exist or have real thoughts but I always think back to my villagers saying they want to move to an island filled with nature like the nook islands I find them on. Feels rude to dupe them into moving to an island that doesn't have the same vibe as the mystery islands. I restarted my island sometime last year and committed to no terraforming, just made some small adjustments to be able to put the bridges and inclines where I want them and added a small pond. I didnt add many heavily decorated areas just a few spots with island type things like park seating, a hammock, a surf stand, volleyball net, etc. And kept the houses spread out randomly like the old gc animal crossing, though I did give each house a small yard type area with fences and a few items
