PC Sales ChartsGonna try something new this week. Something a little...fairer. While we appreciate the lengths the NPD Group go to in providing us with weekly sales data for the PC gaming market, the fact they cover only bricks-n-mortar sales skews the data somewhat, what with so many people buying their shit from Steam these days. So this week, we're going to run two charts. The NPD charts, and the Steam charts. Give you a clearer overall picture of how the PC market's shaping up. First, the NPD data for the week ending October 11: 1. Spore 2. Nancy Drew: The Haunting of Castle Malloy 3. Warhammer Online: Age Of Reckoning 4. Civilization IV: Colonization 5. The Sims 2 Apartment Life Expansion Pack 6. WoW: Battle Chest 7. The Sims 2 Double Deluxe 8. World Of Warcraft 9. Brothers In Arms: Hell's Highway 10. Crysis Warhead And now, Steam's top sellers (as of today): 1. Left 4 Dead (pre-sale) 2. X3: Terran Conflict 3. Counter-Strike: Source 4. World of Goo 5. Team Fortress 2 6. Counter-Strike 7. Call of Duty 4 8. Red Orchestra 9. The Orange Box 10. Peggle Nights
