Variety.

I played for about a month and a half and then quit – I got bored. My main hero was level 30, and judging by the tavern, he was the strongest, but defeating the remaining neutral creatures was just a matter of time. It's unclear what the point of the gameplay is, and why they're turning "Heroes" into a different game with some kind of secrets and a lack of strategy as such. Aren't there enough other games already? And the presented map, although it seems to be made with love, looks like... a pointless grind with an unknown ending. In short, my condolences to the author, and hello to everyone else.
