To add onto this-
The final chamber before the escape sequence in the first game is some legitimate "wtf am I supposed to do" kinda stuff the first time and I felt like I was Einstein figuring it out myself
And I don't think a single Portal 2 puzzle ever reaches that high pfft

Portal 2 (Single Player, 2011)
Not as good as the first, but definitely fun!
I think the puzzles in the first one were more satisfying and interesting to solve but the story was definitely worth the price of admission. GLaDOS continues to be a highlight!
Wheatley sucks tho.
