Pathologic is a bit frustrating. the first game's story and world are entrancing but the gameplay is shit, 95% slowly walking broken up by the excitement of digging though trash, so the sequels are remakes of the first game's story but also not. The series is filled to the brim with meta shit including playing with the fact the games being a sequal. The 1st game had 3 characters with diffrent routes and 2 is a reinmagining of the perspective of the bachelor while 3 is the Haruspex's.
It's a very messy series, 2s an actual game and 3 is apperatetly even better, don't know personally since it came out just today. I recommend at least playing around in 1 just to feel the vibes but don't push yourself if you're getting bored to tears then just watch a long play or something, then play 2 and 3.
