For me, though, Portal 2 peaks late.
Its Chapter 9: The Part Where He Kills You!
Mmm, love that part.
TPWHKY begins wonderfully: by almost literally knocking you off balance.
In other words, its hardly a dumb action sequence, and theres thought behind those spike plates.
Wheatleys murder attempts contrast nicely with those of GLaDOS, in the similarly climactic breakout portion of the originalPortal.
Its funny, and stupid, but also smart.
It is that part, I suppose.
