A great little thing of a game. It has X-COM's turn-based grid-combat but simplified. The combat works fine and is a lot of fun.
For me, the core of the game is the century-spanning "Realm-Management". You build keeps that house your bloodlines which produce new heroes. In contrast to X-COM your Heroes will not be present for the whole game, since humans only live so long. That means you might be fighting a battle with one of your heroes but in the next he will be dead and you might have recruited his daughter that carries her father's relic-weapon into the next battle.
You can mess up a bit without knowing. I did not think too hard about the early years and lost the ability to train new caberjacks, one of the hero classes that is mostly a tanky melee fighter. So I fought the game mostly with alchemists and hunters and their expanded classes since I was unable to get these caberjacks back into the bloodlines.
Nonetheless, the 12 hrs on normal difficulty were a blast. In the end quite literally.
