"I second the idea of a supernatural AAR. Might I suggest Crusader Kings? The way the AI acts is almost supernatural at times, and the era is ripe for chivalric knights, damsels in distress, dragons and wizards!
"On a side note, I'd like to make the case for more AARs for the 1338 scenario. It appears to be much under-valued among authAARs, perhaps for its late start date. But I see that as a virtue, when you consider the glacial pace of most CK AARs. Furthermore, it has a number of interesting set-ups. The mongols are a real, established threat, as are the Ottomans in Asia minor. A whole host of interesting characters awaits - Edward, the Black Prince, the Viscontis of Milan, the Linguisans of Cyrpus, etc. I'd like to try my hand at a 1338 AAR myself sometime, but I'm too busy right now. Maybe someone else will take up the challenge."
