"Roll dice and kick ass!"
Yea I know. I wish it had one too. I think Ewe is a big fan of Zun Tsu. I have to admit the artwork is pretty, but vassal is definitely the most flexible in playing, finding online opponents, expansions, creating new scenarios, and logged play.
Plus apparently Zun Tsu on Firefox requires an extentsion which hasn't been updated to the latest version of the browser.
