Battle of Gods
It has a Turn based Strategy feel like heroes and also a RPG style like diablo because every battle is in real time and you can control the outcome with your hero and army.
You can build a settlement, recruit an army, explore a world, finish quests, fight monsters. You control one or more heroes and earn experience and items, gold resources.
They will soon add kingdoms, where you will be able to start wars against other kingdoms and siege castles.
I really recommend this game because of the game-play and strategy factor, and real time battles.
