This is my first AAR ever, so be lenient. Below are the principles I usually play by, this game included:
1.Roleplay. This means that I generally try to behave according to the personality I envision for my ruler. So if he is Valorous, I will never shy away from battle, etc. I also don't do world conquests unless I have to; generally I also limit my conquering to the historically plausible. My characters don't want to rule the world (well, usually), they want to rule what is their right.
2.Take what you are given and run with it. This means that if I get a less than good son, I won't assassinate him (unless my character happens to be an evil child-murdering bastard). If he happens to inherit, tough luck - I'll play him, though I might try to find a good wife in the hopes of getting better heirs for him.
So, without further ado...
