Yea I didn't realize staying up in Nameless' grill wasn't a good idea until the latest time I beat him, but otherwise Peak is my least favourite if only cause it has the most framerate drops for me, as well as castle wall/early Lothric and Farron Keep. Basically anything that doesn't run as smooth as it should blows in an unfortunate way. Irithyll is definitely my favourite area, though I don't really care for one quarter of Anor Londo outside of it being a novelty area. My first playthrough can be summed up with "Does Not Open From This Side: the Game." Seriously every fkn door
