Heavily recommended for any turn-based strategy (or Heroes of Might and Magic) fan.
It is very addictive if you are into turn-based fantasy games. Hero developments and building options are strong factors in the game and the progressive order in which you get exposed to new units and new combinations is a miraculous fun journey. The art of Disciples II is also one reason why it appeals to me. It has a very distinct and enigmatic Masqueradian look that is quite indie yet detailed.
Moreover, given that it has 4 very distinct and interesting factions, namely the Empire(humans), Mountain Clans(dwarves), Legions of the Damned(demons) and Undead Hordes(er...undead), I find myself unwilling to put the game down till I managed to unlock every unit from every race. There is simply no stopping once you start your first game, and every mission map offers new playing strategies, so you can't get bored with it.
