there has to be some misinformation about this expansion or addon.

namely the news was so rushed that medieval 2:kingdoms failed to have the total war stamped to it.

and i would seriously urge sega caution on even thinking on the expansion until they get the new game mechanics fixed.

they could just be simple historical type campaigns with story lines. and the new units and additional factions part are intended for the main game.

this would sound like a more realistic assumption. except how they would factor in the new campaign maps. which brings up another question since it would have taken less work to add extensions to the existing map instead of making seperate ones.

the only reason i can think they did this was because of the system demands that would be needed to maintain all the factions and extra area of a larger map.

these are just some of my opinions.
