User blog comment:JoePlay/Dead Rising 2: Case 0 sells over 300,000 in first week/@comment-2121501-20100908175911

Absolutely worth it, and absolutely great that it's sold as well as it has.

I only hope that other publishers realize don't start charging for demos and use this as their reasoning. In fact, I think the best term I've seen used for Case Zero was not "demo", but rather "Pre-LC".
