Bloodborne is my favorite easily, but Dark Souls was a lot more addictive (brighter colors and more varied environments probably helped with that)
Honestly I'm at a point in DS3 where I have like 4 bosses left (I've reached all of them, sans the final 4th) but I haven't really felt the urge to finish it. Same shit happened in Bloodborne DLC, got up to Maria and just felt like I had enough of the game. Ludwig was the GOAT boss for me anyways lol
It also sucks when I'm not really touching either but I also don't want to delete them from my PS4 harddrive, since Bloodborne has like what....25+ gigs to download
