Disciples III - Review @ The Guardian

This review of Disciples III at The Guardian carries a score of 2/5, though the short text makes it hard to really judge the issues.  Difficulty and some AI problems seem to be the main complaint:

Combat features imaginative locations that offer more than the usual bland hexes to stand on. Some offer bonuses to magic users, ranged or melee combat, making battles a satisfyingly tactical affair where both defensive and offensive formations have their merit. However, there are irritating lapses in logic. For instance, archers who can fire through solid rock, or heroes who die despite having an inventory crammed full of healing potions. Even worse, unlike some RPGs, D3R doesn't lay these challenges in a gentle learning curve. Very early on, my band of level 1 heroes found itself up against a level 33 Orc which proceeded to kick seven bells out of them every time.
