Tournaments in this version are doomed: there is too much randomness. This is especially critical for arenas: in the same battle, you can get an arena where you are 100% going to lose, and an arena where you don't even have to think much to win (for example, a node in the center of the field, and ravines to the left and right).
The plot is still satisfying (this Inoel is just amazing :). I haven't played Disciples before this part at all, but about the balance of factions (at least, I'll say about the Empire and the elves: it doesn't exist). I liked the system of gaining experience for warriors, but again, it is implemented poorly: incomprehensible jumps through levels (it was level 5, then it became level 13). Experience is gained too quickly (I'm playing on High difficulty), which may be good, because the maps are small.
The AI, however, is as stupid as everywhere else. We kill ranged troops and mages. We put a tank in a defensive stance. The infantry stupidly attacks the tank, naturally, they don't cause much damage, and we heal everyone with Inoel. Even the most difficult battle is won with minimal health loss.
Well, and crashes, of course, spoil the picture. Despite all the criticism above, I liked the game. There is something charming about it that makes you want to sit down and play again, despite the risk of another crash :) Maybe it's because I've played Heroes too much? :)
