The problem with invaders choosing, is that no army would choose to fight Tuareg's in the desert  . but as a nomadic desert people this is where they would choose to stand and defend or harass attacking armies

But were they rivers that blocked off a side of the army, forming an impenetrable barrier or they played a role but were fordable?

I'd love to know the stats on other places. I reckon maybe 1/3 of my games have a river or coast. Pretty sure it wasn't that high I'm getting used to it now, I figure it is just a rules thing to knock horse archer armies down a bit in effectiveness...

Most battles next to rivers had them unfordable obstacles playing no roll at all.  One possibility for the future is to allow the invader to choose which territory type from the defenders list is used - choosing their line of attack.  Haven't thought through all the consequences yet so if you have time to consider ....

Leave as is, seems to be working IMO.
