I was really picky with my maps, my old and new towns both needed:
Apples
A river entirely along the top 2 acres of the town (top half, so only 15A, 16D or 26D or their reverse maps on
here.)
Non-square grass
Plaza also only on top half of town, above river if possible.
One long beach with both ramps.
No sections of beach only 1/2 squares wide. ~ this really randomly bothers me, and happened too often on the corner of town
Town hall and train station both not green.
No villagers living above the river.
Clear secluded bit for my house ~ rocks always appeared where I wanted to live. <_<; with space for a garden.
And several villagers would be insta-reset. ~ Opal, Vladimir and Velma spring to mind, as I don't even want to see them on main street after leaving.
I then had a point system after that if I found 5 negatives with the town I'd reset, things that got points were;
No of ponds minus 2, were a point each.
Overly wiggly river/cliff edge.
1 for each villager I really disliked but could stand to live with.
1 if I couldn't get Cafe/Police station where I planned them.
1 if it was circle grass.
1 for a vertical south ramp.
Can't remember all that list now, suffice to say I was really really picky. First town took 115 resets and about 12 hours on release day, new town took 166 over 4 days. Though these criteria didn't really change in the 4 months between my towns, and I cant flaw my town now.
