I played Portal 2. I loved it. I loved it so hard, I made fan art with MS-paint.
... And on second thought, maybe I didn't love it hard enough. Glados looks like shit, and so does that space core. Effectively, that lays the rest of my mouse-art prowess on the single stick dog in the bottom left corner. And he's not all that spectacular.
Anyhow, game was good. Great humor. Etc. Some of it did seem a little wordy, and they could have done a bit better combining story with game play. (It seemed rather parsed between playing bit and getting drug around while having the story told to me.) A lot of the puzzles seem honestly oriented on finding a single random bit of portable surface (or creating one), or finding a way to fling across an uncrossable expanse. I would have liked to have seen some more of the logic
based puzzles there was in the first game, rather than so much physics
based puzzles. And there is a distinct difference, imho.
As for the co-op, fun fun fun with absolutely ZERO replay value. Honestly. The only redeeming feature is that there should soon be downloadable content for Steam users.
Anyhow, there's my two cents on the game. o3o
