He didn't ask for it!
The Kingdoms capaigns went into a bit more detail with this, paritcularly the special "Hero" characters each faction had in the Crusades campaign.Well, they do try to give you historical characters to start out with in RTW and M2TW.
Perhaps morphing into the Apocalyptica version if you start losing, to add that delightful feeling of discordant tension.I've decided that any future game which features attacking a fortress on a mountaintop should play as a special battle music "In the Hall of the Mountain King" by Edvard Grieg.
Age of Empires is **** though. Made into a total war game, it would be really good.
Apocalyptica is probably the coolest band ever.
