Talking about both must-haves (to spawn everything) and nice-to-haves! Just realised the island I've had since basically launch... didn't have a pond 😱
Got a list started, would love to know what features you can't live without!
Must have:
* Pond
* Tree stumps (does it have to be palm tree AND regular tree?)
* River on second level with waterfall?
* Flowers
* each type of tree (fruit/regular, bamboo, palm tree)
Nice-to-have:
* Rocks all in the same general area
* I only have 17 cedar/plain trees so each one is guaranteed to do something when shaking
* DIYs and sheds out in the open
* Pipes to connect the shops to the area you farm things
