Like those older games "battles" can take up to an hour to finish, but I feel I have accomplished something at the end. On the down side the mage/cleric units have very limited use (so far anyway). Also the combat machanics are simplified quite a bit compared to other turn based combat games.
A review I read for the game stated 40 hours is the average game time to complete. So it looks like I will be playing this one for a while yet.
