Excellent price on Limbo if you haven't picked it up yet. I also thought it was a tad over-hyped but it's still a good game. I played through the original ZA title and like it well enough for what it was. It's not one I ever went back to play after 100% the achievements but I easily felt I got $5 worth of entertainment from it. The demo for the sequel was enough to make me not purchase it. As others have said it feels quite a bit different from the first. I also found the voice acting extremely obnoxious.
