I'm not a "Soulsborne" fan per se, but I played Dark Souls for the first time just over a year ago and it enthralled me. There are just so many exciting moments in that game - the hellkite dragon, getting chased by a Black Knight, walking into the Undead Parish and getting hit by a beam of light from out of nowhere, fighting gaping Gaping Dragon, crossing Blight Town and then finding out you can just waltz on over to Firelink Shrine, chilling in Dukes Archives etc. The environment designs are really inspired. Playing DS1 brought back those feelings that I used to get playing Ocarina of Time all those years ago.
All other 'Souls-like' games seem uninspired in comparison. I unfortunately never got to play BB, but I did play Sekiro for a little bit and that just seems like a shit game to me.
