The Witcher 3. The base game is totally complete as is, but you get a ton of free DLC that’s mostly cosmetic, but it also has some neat gear and additional sidequwsts in a game where sidequwsts are done amazingly anyway. The Hearts of Stone DLC is a big new addition to the game’s main region with its own sidequwsts, the most satisfying bosses in the game, as well as probably the best story on the human condition I’ve seen in gaming. Blood and Wine has a world that puts all the knowledge the team gained from the main game to create something truly magnificent. It also has the best fanservice for the book fans in the series, making the series end on a very high note. It’s also as big if not bigger than most games nowadays.

So yeah, the free DLCs are good and the paid ones are well worth the price and don’t feel like they’re added missing content from the main game at all
