The Warcraft III Battle Chest joined the six Blizzard games that were already on March's list, meaning that Blizzard served up 35% of the top 20--more than any other studio--all by itself. World of Warcraft's Lich King expansion regained the top spot from Creative Assembly's Empire: Total War, and Relic's Dawn of War II dropped from #4 to #15.

Also of interest is the sudden appearance of Illusion Softworks' 2003 shooter Hidden & Dangerous 2 at #20. I'm sure the $5 price helped, but that's certainly an odd revival.
