These are the mods I currently use with Stellaris. New races, more interesting game systems, lots of music, lots of graphic improvements, and insufferable elves you can shoot out of the sky.

I've updated this into sub-collections so you can pick and choose (you may not want any new game systems, or download gigabytes of music). It does mean you can't just hit one button to subscribe to everything, now you have to hit five buttons. #first_empire_problems

Note that some mods (mostly music) will flag as incompatible with the current version. They will still work normally; I've tested everything in this collection.

Total conversions should be used by themselves, with the exception of Star Trek: New Horizons, which has its own collection (and is really its own game)
