The Undertale Genocide Route is amazingly well done. The Pacifist plot twists are way too obvious though. Aside from one, which you can only learn by backtracking after it, and is never even mentioned making predicting it literally impossible, you can figure them out the instant the thing related to it is introduced. Like who Flowey is, who the first human was, so on.

Chara and Asriel? Regardless, I prefer genocide only because of the Sans fight.
