Agreed, that's a personal favorite. We mostly play the base game (with all the DLC; one nice thing is that it's enough for the host to have them).

I've tried some mods, but Star wars Interregnum seems to crash for me after a while. I think it's a known issue on Linux: https://github.com/ValveSoftware/Proton/issues/265#issuecomm...

These mods seem nice, but I am not so much into these other universes, and the base game is pretty solid already. I might try them again at some point for more variety, notably Sins of the Prophets.
