I always loved the fact that heroes has some RPG element that help the strategy part.
But all the demos i saw focus a lot on the hero advancing and battling. But it always felt like i was looking to an RPG demo more than a strategy game, they show the nice graphics battle, etc. But very little i have seen about the strategy part of the game, in fact i always see one hero and one castle. i want to see more about the features of the town, and how map does help the strategy game more.
Battle is important yes, but more than it is map adventure, and the only thing i see is a hero walking and killing.
