Exactly what I have been waiting for. This is one of the top 5 games to come out in 2008.
The game gives you the feeling of constant achievement, and growth. Its subtle, as you run around collecting runes, increasing your abilities and getting rich, while slaying the various evil armies that infest the lands, which you gradually make safe for all. This in turn make it easier to run around, replenish your armies and complete the quests you have accepted.
King's Bounty is a game worth trying out. Its may not be for everyone, but if it is for you, you will have nothing but a good immersive experience.
