As nice as this engine is Demi, and as powerful too, it does come with a great complexity. HeroEngine didn't make it easier to make an MMORPG with their complete package, but they made it a bit easier to grasp with some simplified concepts in the front end.
Even if you fail with HeroEngine (some already gave up because of lack of resources), it does not mean that you have to quit your dream, for there are others roads that you can take.
It's nice to give indies their dream, but the indies themselves have to wake up to make their dreams come true.
