I would love a campaign that starts in the 12th century "Horse and Bow" era and allows the player to progress right up to the 16th/17th Centuries. Could also include the Yuan/Mongol invasions of the 13th Century...

And please NO risk-like strategic map - that was my biggest peeve with the original. Japan is a rugged, mountainous country and armies were usually confined to roads for a reason

Oh and YAH!
