This is a week old, but in case you haven't seen it: here is a hands-on preview of Costume Quest, courtesy of Giant Bomb. It's a little spoilerish for the hardcore "I don't want spoilers!" among you and opens-up with the witty banter game reviewers are so renowned for, but is still worth a watch. Don't make me tell you again.

Good video. The guys at Giant Bomb are doing some of the best games media work there is, and they're worth keeping an eye on as they have a lot of time for companies like Double Fine and Telltale. They regularly talk about TT games on their popular podcast and are probably responsible for more than a few more sales as a result.
