Just a few dlc/expansion packs that were totally worth their money
All Rimworld expansions.
Diablo 3 reaper of souls/ D2 lord of destruction
The witcher blood and wine (?)
Ballad of gay tony
Star craft ones
Red alert yuris revenge
Horizon zero dawn frozen wilds
Etc… There are good expansions that are totally worth their money and add to the overall game.
That being said, I’m not a huge dlc fan and rarely spend money on them if they don’t really add to the game. More partial to spend on dlc for smaller studio games rather than large ones.
