Was just a silly thought, but Cata could totally fit into some sort of space survival sim. How likely could you see it?
You have a choice of a few starting scenarios with various levels of viability, in a setting where a once solarsystem spanning civilization suffered a sudden extreme schism or cataclysm, and is in a somewhat similar situation to catadda but in a space setting.
You’d probably have extra worries, like life support and having to deal with gravity, as well as needing a pressurized environment. Instead of taking place in a bunch of towns it’d take place in some sector of the solar system, and the ground level would be the ‘overworld map’. Instead of direct zlevels, “going down in zlevel” would take you into the location, like if you went down over an asteroid group you’d be on a map of asteroids, or on a moon of a planet you’d be on that moon.
Vehicles or at least some sort of conveyance would probably be much more significance.
The crafting system could probably be kept, just with some additions/removal and re flavouring for the higher tech levels. Could see remote resource gathering drones being useful.
You could also have randomized animals and mobs on the few relatively habitable places.
Instead of moving to another part of new england when you cross past the border, you’d cross into another sector of the solar system. Probably would take more effort.
Stuff like that. One scenario could have you starting on a run down space station, another could start you on a failed moon colony, another you could be on one of the colonized planets that’s gone severely downhill.
Could see the first implementation of car vs car combat.
