I map reset for about 2-hours on launch day. I also didn't know what to look for back then, so I only based my choices on airport colour, fruit, and resident services being close to the airport. I regret the last one a lot LOL. Now I know there's things like thick outcrops, pier size, large beach rocks, and native flowers etc. Anyways even after learning all these things I didn't feel like resetting my island again. I don't particularly like my map much but I have reworked it countless of times to settle with something I'm happy with!
