I played Costume Quest, but don't think I finished it.

This seemed short and I certainly enjoyed playing it while I was playing it, so that's good. And the story line was fun and it never got overly bogged down at any point.

My 4 and a half year old nagged me to keep playing this one. We had to take a break about halfway through as the trick or treating was freaking her out, but a few weeks later she was asking for us to play it again.

She was rather grumpy that it ended, but there was an achievement for honking the horn 1000 times, so she got to spend some time pressing the same button over and over again

I got this one for free with Games for Gold, so from that point of view it was certainly worth what I paid for it
