Yes, a Text File for each scenario that contains specifics for that scenario. Each one is 2.5mb, otherwise I would post one of mine here as an example [I 'created' a few scenarios, or rather 'my versions' of scenarios]. These types of files are sometimes a pain because if you make a mistake, the scenario is unplayable. Alternatively, a game such as TOAW will generally let you play with a mistake!
In addition to everything else, earlier versions of this game had Quantitative Supply, but for the newer version it was eliminated. To me this was one of the steps backward and a huge one. Quantitative Supply, for those not familiar, is the V4V type supply system where by you get what supply you are assigned, and you only get so much. All other games give all units everything, or something similar, so not a good model of Logistics.
An example of another step backwards from earlier versions, how Advance After Combat is handled. Used to be that all units eligible to advance were highlighted in blue, you click on a unit to advance. With the new version, after combat you get the pop-up seen below. Because of these you can't tell if the defender retreated or was eliminated, what the terrain under the units is, what units are in an attacking stack, and no matter where you move them they pop back to cover the combat area. The pop-ups cycle thru each unit that attacked one by one. It's really annoying, the old way was so much better.
