Top 20 PC Game Sales in North America in May

The NPD Group announced today the PC game sales rankings for North America in May, with the newly launched online game masterpiece "Age of Conan: Hyborian Adventures" immediately claiming the top spot. Traditional standalone games are expected to see significant changes. Within the TOP20, EA and Blizzard still dominate. Players might be getting tired of this ranking. When will there be major changes? If you have time, even a cursory look can help you find some decent items. I often take big risks, but the distribution isn't as even; the central communities are relatively dense, making it a noisy downtown area.
