I don't agree with this at all. Portal 2 might be longer but to be honest I liked it far less than the first game. It feels like despite the game being twice as long as the first one it just spends most of its time teaching you the same things but now with humor that I didn't particularly find funny. Old Aperture was cool aesthetically and I did like the later levels when the difficulty picks up but by that point I just wanted to be done with the game.
