Saling The World on Gamasutra has this week's multiplatform game sales figures showing StarCraft II leading all games in sales in North America and the UK. This is not so common for a non-console title these days, and the data are from yesterday, so this encompasses only two days of SC2 sales. They also have the list of the top five PC titles in North America, indicating a good week for Blizzard: 1. Starcraft II: Wings of Liberty (Blizzard), 2. Starcraft II: Wings of Liberty - Collector's Edition (Blizzard), 3. Starcraft Battle Chest (Blizzard), 4. World of Warcraft: The Burning Crusade (Blizzard), 5. World of Warcraft (Blizzard).
