For me, this would be Dark Souls 2. From looking around on discussion sites, DS2 seems to be the “black sheep” of the SoulsBorne franchise, and I’ll never understand why. The game has its issues, absolutely. But I find myself going back to it far more than any of the other titles from the same developer
I’ll always acknowledge the shortcomings that the game has, but I’ll also defend it as much as possible, and point out everything right that the game did. It’s my favorite game in the series, even though that’s probably a very unpopular take
