What a glorious disaster. Like everyone else I don't know yet who to blame for this, but... that won't stop me from giving it a try! Bwahaha!
1st place: WB, because I've disliked their anticonsumer practices for a while now and I've been itching to find a place of honour for them in my shit list. Well, this is it: you made it guys.
2nd place: Rocksteady. I don't even care if the "suits" of WB forced then to outsource the pc port: they fucked up. It is still their baby, their logo at the start of the game.
3rd place: Iron Galaxy. Kind of feeling bad for them, since they're the easiest target. Maybe they messed up, maybe they didn't... one thing for sure is that this port is the first thing that will come to my mind whenever I see their name/logo in the future.
