Oh dear, this shows how a campaign must NOT be done.
Playability - All the scenario's are either random maps, with all buildings and a small force or Fixed Force where you have about 400ish units and kill a force twice that much, and that is tedious
Balance - The Scenario difficulty Ranges from hard to impossible, since in one scenario you have lots of longbowmen aganist alot of paladins. Probably the only way to win is through cheating.
Creativity - All the objectives were Kill them all not creative IMO.
Map Design - The Best Part of the campaign but still awful there was some trees, cliffs and water, hardly any eye candy and mainly grass.
Story\Instructions - You (The English) go around killing all the supporters of king Eric the Red of the vikings because of an argument over a game of chess, That's it, not great story, As for Instructions they were the worst part some of the instructions were like "The Viking King Eric The Red is furious over a game of chess and his army has invaded England, Kill the Eric the Red". First Thing there was no Eric the red the real objective was Kill them all.
