Nice to know I'm not alone. I just got this game and after two frustrating sessions, I'm ready to toss it back. I spent about an hour and a half with the tutorial and, forced to abandon it in favor of earning a living, I was astounded that I couldn't save the game. Beware future travelers who pass this way.
In any case, I found the interface confusing and extremely unintuitive. I would cite in particular the way that the unit and activity sprites all seem to crowd on top of each other so that it's next to impossible to sort them out. Then, finding myself engaged in a battle with the locals of Munster, it was never clear to me how this exchange was going or precisely what the outcome was. There seem to be some places that units can be moved and others where they cannot but what those constraints might be I have been unable to determine. The manual, while extensive and full of information, seems to be long on concepts and maddeningly short on mechanics (an index or at least a table of contents would be much appreciated). Like many of you I tried the Grand Campaign in my next session but apparently made a grave mistake by playing England. After much trial and error I finally managed to get some troops on transports (the manual seems to contain erroneous advice in this regard) but once off the coast of France they stubbornly refused to disembark (their reasons remain obscure). In any case, the fleet floated about the Bay of Biscay for so long that they finally sank (I don't know whether to be pleased or frustrated by the game's demand that Guyenne be annexed. Guyenne [or Aquitaine] came to England with Eleanor and was lost again in the 100 Years War. It was thus an old and irritating bone of contention regardless of whether or not it was worth anything. In EU, apparently, one can nudge history but not wrestle it to the ground. I suppose that I'm too accustomed to God games. C'est la guere). Failing my first mission, I then tried to vassalize Scotland but my (remaining) troops simply refused to march into that cold and lonely place (the Firth? Hadrian's wall?). I was by this time so vexed by unanswered questions not to mention unimplemented commands that I chose the better part of valor and surrendered (to fate? fatique? my inner demons?).
Well, should I give up? Am I just hard to please (petulant old fart that I am)?
Or should I take your collective advice and try it again with Russia? Did someone say Portugal? FantasyLand?
