The sequel bagged a million sales in the first day, and another 500,000 in the second, making it the fastest selling strategy game of all time and the bestselling PC game this year. Blizzard, of course, says it's pleased with the title's reception thus far, despite a handful of complaints about game balance and Battle.net features -- some of which should be resolved in the first retail patch this month.
Many of the changes were detailed in a "Situation Report" last week. They're mostly just race balance tweaks so far, but Blizzard says it has "mid- to long-term plans" for custom games and social features such as chat channels, which would make it easier for players to meet in-game.
