I don't know... since I played episode 10 I have the feeling that the only paths that won't end in disaster are Josy, Sage and... I don't believe I'm saying this... Quinn. Every other path gives me this looming sense of dread.
What complicates things is that we have the MC's love life, the storylines of the various protagonists, and the possibility of one influencing the other.
We don't know how DPC is going to deal with this, does he keep score and at the end of the game, if we don't have such and such a score, the relationship will be over?
Bella, we've had Cathy's panties trap, and I thought we'd have others, like dating Jill and Bella at the same time, or cheating on the exam. I'm very surprised it didn't have consequences. I think that if we accumulate too many bad choices, we'll end up paying for it before the end of the game.
Jill, apart from Bianca's ass, there don't seem to be any obstacles to their relationship. Except maybe if we accumulate too many DIK choices, and the MC ends up looking too much like a bad boy, it could have a negative effect.
Sage, there's the obvious trap of sleeping with Jade, and maybe the restaurant, but other than that, no danger in sight.
M+J, obviously we need to balance the trouple, and then, I don't really see any obstacle. In any case, DPC owes us a trouple, the last one he burnt down...
Quinn, I don't know what to think with her. If Burke is indeed a sexual predator who forces college girls to sleep with him for a scholarship, and Quinn provides him with fresh meat, she deserves to end up in the gutter. If not, I could see her leaving to start a new life somewhere else, and starting from scratch, without the MC because broccoli's no good, and because it would remind her of the life she wants to leave behind.
In any case, I see nothing to indicate that certain paths are automatically doomed, except of course according to the player's various choices. Apart from the Cathy/Bella and Jade/Sage traps, which were vicious because you never see it coming for one, and for the other you don't know the connection, the rest of the traps are quite visible.
