Blizzard is playing the role of a big-budget producer. If Blizzard had gone after Torchlight and built a strong off-line SP game, people would be complaining about how those "big" companies are being bullies to the little guys. They can't win no matter what they do. People need to put money toward products that fit themselves and stop whining. The marketplace is big enough for everyone and varies enough for many different flavors of games like this.
