Blizzard is easily one of the best, if not THE best developer in the world. One big reason why is because they are a bit conservative. The perfect core game mechanics, include some new twists, polish the game so it shines like the sun, and balance gameplay to the Nth degree. They don't often bring out new IPs, but when they do those IPs are incredibly good games. Warcraft... Diablo... Starcraft... World of Warcraft... you can't argue with that lineup. I'd rather Blizzard continued their path, improving on their stable of excellent games and only bringing new IPs to bear when the match the quality of their previous work. Why would we want them spewing out crap new IPs every other year and ruining the name they've carefully built? There is a reason why Blizzard is so successful, why would we want them to change?
