The artificial intelligence in this game is nice except for the generals who commit suicide on the battlefield by storming into the heat of the battle. Sieges are not realistic & detailed enough. I like turn based game more than real time games (like Age of Empires). You're not gonna belief this - I can't get hold of the expansion pack (Viking Invasion) - not available in South Africa (well, I couldn't find 1 yet), & not shipped to RSA from USA or UK. Great game!
