Also, GLaDoS is still the best videogame villain of all time. (Of all time!)
Definitely recommended if you liked the first one, and/or if you enjoy a good puzzle game with a lot of sly humor. The only downside is that it still seemed short to me, although this is probably because I'm so used to RPGs that last billions of hours. Then again, I'm not sure how much longer this could have been without feeling repetitive. So, thumbs up, way up, and I'm already starting to wonder if they can pull off a third.
