But once the single player game is finished, nothing much to go back to. Except perhaps the armaggedon level. Becomes a little samey towards the end. Short but sweet. Standard 'god' goals i.e. destroy other people with your people.
Control system is awkward and takes a while to learn, similar to magic carpet.
Levels are won by utilising new spells and weapons efficiently against the larger armys of poor AI controled opponents. Magic carpet style. Fast graphics engine. Nothing amazing but perfectly sufficient. Adds alot to the style and feel of the game.
