Yeah, I want it purely for aesthetics. I like generating 100% of the planet, and sending colonies to far-flung places via dev mode instant travel to settle in isolation, so I spend a decent amount of time looking at the world map. It just bothers me when it’s mostly land. It’s ugly, imo, and you get fewer interesting land/climate combos, even with expanded biomes. Also one of my mods adds things washing up on the beach, like organs, so I'm a big fan of ocean-adjacent tiles.

Honestly I haven't gotten the new DLC, and probably wont, so I don’t really know anything about the space stuff. I have way too much time and energy invested in my collection of mods and don't have any interest in doing it again (I manage them manually because I don't use steam, so updating/replacing a thousand mods is a big project)

I’ve been playing whiskerwood on and off, its in early access and runs for shit on my crap windows computer, but it’s all islands and it seems they'll be adding more to water navigation (last patch I installed added ferries and boat docks, and that was a few months ago). I enjoy that sort of thing too, but I don't think rimworld really needs it.
