Hopping from island to island to get more rocks, logs & sticks, etc. is really fun, but I hit a wall when I found out almost nothing respawns.
There’s only so many islands to harvest, and there’s no reason to ever return to any of them once stripped of resources.
It would give players more of an incentive to bounce around the islands if they knew that stuff respawns on islands that the player hasn’t visited in a while. Palm trees/small trees eventually grow back, new rocks wash up on the shore, etc…
