For me, a friend let me borrow Demon Souls but it just didn’t click. Years later, I played Dark Souls and it immediately became my favorite game. DS2 was my least favorite of the series, in equal parts because of the much different control/feel and also the wasted mandatory levels you have to spend to get reasonable i-frames. It just feels clunky compared to the rest of the series. I do really like the level design and environments though.
