This is my favorite game of all time for so many reasons. The comedy is top notch between Wheatley, GlaDos, and Cave Johnson. Test chambers were fun, however the one problem I have with the game is the old Aperture because some of the puzzles were too difficult, but that's definitely a me thing. Multiplayer Is a blast and one of the best in the genre. I didn't think that there were many ways to improve on Portal 1, but I was pleasantly surprised.
