I really enjoy playing this game. It reminds of a roguelike but is more static - for example every playthrough is on the same map with the same basic quests; the variation comes in with random drops, dialog outcomes, etc. Overall the game nails it on atmosphere (dark/steampunkish) and I am enjoying the learning curve as well as the difficulty. Might be a little expensive in comparison to similar games but it's worth a try if a fan of the genre.
With over 200 hours logged on each of the King's Bounty games I can say that I love the series. The game plays similar to Heroes of Might and Magic but perhaps more hero focused and in 3D, and pulls it off very well. Lots of units, interesting (numerous) quests and plot, and all around fun.
