Graphics, Sound, etc. The world is a true 3D globe which can be rotated and seen from any vantage point. It's also ultimately morphable. Spells can change the landscape, raising and lowering land, flooding areas, causing fire to rain from the sky or a volcano to rise in the middle of an enemy town with lava flowing and fires raging. It all looks really cool, especially with a Direct3D compatible video card.

They are appropriate to the environment, but lacked the appeal of your minions in Dungeon Keeper , another Bullfrog game. Music on the other hand was pretty good. It is kept in the background but adds to the game environment nicely. The manual was a bit on the poor side, it did a less than stellar job of presenting how to play the game and was woefully short. Even so, the built in tutorials give you the basics of how to play and control your forces well enough, the foldout quick reference card gives you all the commands at a glance, and the in game encyclopedia gives help on the interface, spells and your forces which is a big help once you find out how it all works.
