Ôk more feedback. I tried the independence route with Baktria and I have conquered four Selecueid cities and won 7 or 8 big battles., still for years now every turn I get the "The Basileus offers forgivemess." event. The armies were always led by family members, I always played them myself. I always attacked. I read the guide, I read the reform req thread. I killed in seperate battles the Basileus and his heir.

edit: while the game continues to break my mind. Report on cavalry. On M difficulty the cavalry certainly has a punch. That seems appropriate.
edit2: A little look at the map. It seems that the blockade in Africa works. Rome has rebelled?!
