Why is football popular, while chess isn't? It's simple. Anyone can watch and understand football, while chess is only for those who are knowledgeable about it. The audience is several orders of magnitude larger. That's the huge difference. The same applies to games. Anyone can play Dota and CS, but Heroes requires you to use your brain. Plus, the longer game duration doesn't fit the WCG format. But, as they say, this has all been discussed a million times.
