I’ll never beat Pathologic (particularly not with Pathologic 2 coming out next year - I’ll be diving into all the alpha builds and such they’re going to release for backers who gave them lots of money (aka me)).
I love CRPGs (Baldur’s Gate, Planescape, Pillars of Eternity, Numenera, etc.) and I will probably never finish any of them because I don’t have that kind of time (correction: I definitely have that kind of time but I spend it doing other nonsense, like replaying the Metal Gear Solid series for the billionth time) and honestly at some point I hit a wall with those games where I’m just tired of it.
I think that’s probably it though. Other games I will never beat are games that I just kind of like but don’t really care about enough to finish, which is… a lot of games.
