When Blizzard announced many, many years ago they were bringing the WarCraft universe to a persistent world, fans of the genre got giddy for one simple reason: Blizzard games actually work when they are released, which is a far cry from the usual MMOG launches of late. While there have been plenty of Blizzard games I haven’t liked, the attention to detail that Blizzard places on their QA allows me to judge the game on their content, not whether it’s a buggy mess.
