So, while we’re all assuming that the cult ending was/is intended for some sort of creepy Halloween DLC, I wanted to throw my idea out there:
Make every character super dark/into a monster. Every dad has something super messed up about them going on and you need to save your dad/join Robert in ridding the world of these monsters.
Damien becomes an actual vampire, drinking the blood of the other beloved characters in the game (Quizmaster Quinn, may you rest in piece).
Joseph is, well, a cult leader possessed by a demon that is getting him to kill others for its own sick pleasure.
Craig has turned into a werewolf, and you must chase him (UUHHHGGG) down before he turns on River who is still strapped to his chest.
Mat, you don’t know what’s wrong…But something’s just…Not right. It’s not actually Mat, but everyone thinks you’re crazy. (Changeling)
Hugo’s son goes mad and kills his father, now Hugo is a ghost and you have to figure out how to bring him back.
Brian…Idk what to do for Brian. Go nuts in the comments. Hell, tell me what each dad should actually be instead of what I just thought of off the top of my head.
Robert’s the only one who hasn’t turned, so he’s the demon hunter of the town. You can either join up with him to save your Dream Daddy; Exorcise Joseph, cure Damien/Craig, find out what’s wrong with Mat, bring Hugo back from the dead, ETC. Or, if Robert’s your Dream Daddy, you help him out in ridding the world of all the other evil dads and adopt all their kids and become the best dads in the world together.
The end. Best Halloween DLC ever. Game Grumps, do this thing or something like it. Don’t make Joseph the only one with something creepy going on. Include everyone in the fun! Make it dark but oddly charming and adorable as you are so good at doing.
