The other problem with the long missions is that if you do end up screwing up and losing your best leader you really have no choice but to start over more often than not. When you've spent 3 hours on a map this can be frustrating. Despite this fault, I really like the elegant game design in Disciples . It doesn't get bogged down in needlessly complex tactical combat and too many features. Graphics, Sound, etc.
Disciples looks pretty good.
While it can only be run at the default 640x480 resolution, a definite drawback, the maps are colorful and attractive. Especially fun is the way the map warps in look as the different factions gain control of new territory. Unit animations on the map look good, you can tell that units are flying, walking, etc. The only complaint I had about the units was that from behind many of the leader types look the same, so it is often hard to tell what sort of leader you are attacking until you join combat. Combat animation is limited to one for each unit type, but they all look good, and some are quite cool indeed.
