I'm not saying you're stupid, just ignorant. But I'm glad you actually understand that the game has a meaty campaign - that took me around 20 hours to complete.
You sort of failed to mention that in your original post.
It's full of voice acting, cinematics, handcrafted bossfights and a ton of extremely detailed assets and visual fidelity.
The real heart of the game, however, is the combat system and the skill system. Animations and the pacing of combat are fantastic - and in this core way, the game is superior to pretty much all other ARPGs out there.
As for how you arrived at 6 maps, I have no idea. It has dozens of maps and visual themes.
The future is bright for the game - and it sold quite a few copies, so that's good.
