About Loyalty and religions I have to say that I'm playng EB with BI, but this two elements of gameplay aren't present anyway.

About the possibility to recruit Legions I have read on some other forum of some other mod that is possible to recruit specific historical legions such as the X Legio Augustea, I think that this is done by building some kind of structure that let you train Legions.

About Natural events I was referring to events such as storms and quakes, that happens so rarely in the game.

I hope you understand cause my english is really bad.
