My personal list:
Sem's Lichtschwert Fix mod-Translates to "Lightsaber Fix" (the creator is German). It removes the collectibles tag from lightsabers, thus allowing you to have multiple households with lightsabers and have duels between them. Pretty much a must if you have Journey to Batuu, imho.
TitanNano's Control Any Sim-Great for those times you want to control multiple Sims without having them in a single household. But this mod hasn't been updated in a year, so I wonder if I should still be using it...
LittleMsSam's SimDa app-Great for those going for the Serial Romantic aspiration! And those wanting to spice up the dating scene in general.
Llazyneiph's Royalty Mod-It has recently been updated to feature a sword fighting system. That's more than enough, but it also has plenty of other mechanics for those who like a feudal system experience.
MCCC-For obvious reasons.
