Hi Steel God.
OCD is my SOP.
I made those entries for Poland 39. In discussions with RickyB we both felt including all scenarios would be best. Players will choose to play any scenario they agree upon. There is nothing to stop that from happening.
While there appears to be no differences between the designated HTH and versus AI only scenarios, in play testing Poland 39, I felt there were subtle differences.
The primary difference is when the scenario is designated for Axis AI, it uses a different PDT file, the one with the name *_entrenchments. You will find the entrenchments have lower values in these scenarios than vs the Polish AI. The values for bridge building are also lower. In some cases the VP requirements are less as well.
The scenarios for Axis AI as HTH possible but with a bias towards the Germans and hence good for novices etc.
Bottom line, players could choose any scenario to play. I and RickyB felt we did not want to have to add scenarios to the DB on a request only basis later.
Hope this explains the reason why all scenarios were included in the Blitz DB.
