I don’t mind if some person the MC is fooling around with explodes a relationship. That’s on him for not sticking to one girl. What really frosts my pastry is if it’s something we can’t help; something unavoidable built into the game, like sitting next to Val on the bus, and suddenly Alexis irrationally loses her shit and breaks up with him again. It’s the stuff you can’t help.
The stuff you can help—yeah, I’m fine with making them causes with big effects. Just make em logically consistent at least.
