You might not be aware but there’s also a fairly content-rich successor project called SpaceStation 14! Its obviously nowhere near as featureful as 13 is, due to lack of development time but has a very active development community around it.
One of the major (imo) improvements is a move to per pixel “real time” movement instead of the tile movement of ss13, it helps make them game feel much more alive and interactive.
Definitely worth a look for fans of ss13, and its also open source and Linux compatible.
