An excellent turn-based game -- balanced gameplay is key to this type of game and it suceeds.
As a turn-based strategy game however, the game excels in every way. The developers put a lot of effort into game balance, unit design and map design and all of the work and thought shows.
If you like games like Heroes of Might and Magic and you want a similar game this is also a bit more difficult that HOMM, the demo of this game is REALLY worth checking out. 1C has put out some incomplete and under-cooked games lately, but this one is a winner.
