Yeah, and I really like the Traditions and "resurrecting" old Legions. A neat mechanic.
Yeah that's one thing I haven't seen anyone else mention. I love that each of my armies has to have a general, can see it leading to some pretty epic civil wars later in the game.
I also like the General mechanic (even though it's a bit of an annoyance that you can't recruit or split forces without a general, overall it helps generate a more intimate feel for my legions and commanders.
