naznatips (on 31 December 2008) We have no reliable way to track PC game sales because at this point so many of them are made online that we would be massively undertracking everything.
MetalGearfan024 (on 22 December 2008) Yeah, Wrath of the Lich King sold up to 2.8 million copies within the first 24 hours of availability and other than that, nobody except the Blizzard sales representatives know how much it's sold since then.
famousringo (on 25 November 2008) VGC simply doesn't track PC games. There is no VGC data for WotLK, so no dales are recorded in the database.
Canyarion (on 21 November 2008) Maybe VGchartz doesn't count it because it's an expansion and not a standalone game?
FaithRaven (on 20 November 2008) Record breaker and no sales recorded?
