I just discovered EB and am interested in dowloading it to my copy of RTW. I have some questions:

1. Are very man terrain features, like forests and rivers, named on the campaign map?

2. About how many new settlements are there for the geographic area covered by RTW? (settlements added to RTW)

3. Are Roman civil wars simulated in any way?

4. Finally, this might be an obvious no, but is it possible to combine EB and Rome Total Realism by downloading them to the same program?

Thanks.
