The pricing of these games is indeed set by the publishers, and the market. They basically all go for 19.95, regardless of how big or small they are, although there are _many_ discounts and sales at the various portals, etc, so it is possible to pay less.

VV2 will be designed to have more diverse reply. These really are designed to be 'software toys' like SimCity, etc, and we are trying to make changes that will make them more unpredictable and less linear.
