Extremely enjoyable game, particularly in campaign mode (I don't think the tactical game compares that well with current Napoleonic and modern games, like CMBB, but I've never tried an ancient/medieval tactical sim before).
I'm having a blast as the Danes- started out 1080 or whatever and have made it to 1357, grabbing Sweden, NOrway, Ireland, Scotland, Wales, Wessex, Livonia, Portugal and Saxony. Waiting for the Spanish or Russ to polish off the French so I can grab the rest of England, then rely on my mighty fleet to keep me safe. Ahhhh, delusions of grandeur......
