Like a lot of people, I cane up with a list of priorities before starting, and then tried to pick a map that met as many of them as possible. I set a limit of how many times I was willing to reset before starting to try to limit how much time I wasted. I ended up getting a map that I liked well enough on reset #4 (so 16 map previews and four actual town visits), and that’s my current island.
I knew I wanted a blue airport, as that didn’t appear to be changeable. I didn’t have a strong preference for river exits, but didn’t want two south exits. Most of my potential maps were either E/S or W/S exits, though, so that didn’t end up factoring into my decision very much.
I wanted apples, but later decided to settle for my second choice, cherries. At this point, I have apples, cherries, and pears (still no peaches or oranges), but I realized that cherries actually suit my island better than apples, so I’m happy with them.
I wanted a somewhat central residential services that wasn’t right in front of the airport. Aside from that, I figured most of the layout could be changed, so I didn’t worry too much about it. And then I got attached to my layout and only made minor changes via terraforming anyway.
I told myself not to worry about animals, as those could change. However, the town I picked ended up having two starters I liked, and they’re both still on my island today.
