I always like the idea of traversing through broken platforms and junk to move about, because it feels like there's always something new to find or a better place to stay at. I'd rather have a survival type of thing of sorts in which you and a group of people walk around and find resources and weapons, and after a timer goes off zombies (now that i think about it just blockheads with guns would work out better) fill in the map and from there its all buggy and jank, which is fun! I know it's probably not easy but if you can't it'd still be fun to just stash treasure chests out and about.
