Games like path of exile, have a permanent world, where they create new ones, with different rules to them, and that keeps their game fresh.
So what if we had two worlds for haven, one permanent and one that ends at a certain point. The characters and their inventorys made on the temporary world would get dumped into the main world after it ends.
There would need to be some special items or rules of the new world, to give extra incentive to create a new character there and play it. For example : animals have 50% more meat+ animals move 50% faster / forageables +100% quality+100% less common foragables. / no fate system. the sky is the limit.
You may think this system divides the already tiny community, but many people have issues with world ending in general, so if a world stayed, you would keep more people, and end up with a bigger community anyways, even with the split.
Considering the changes to death, don't you think it's time?
