I am a bit confused! Interactive History can mean a period, a campaign, a battle etc. - So what is the difference of the two options.

BTW, I would really like to see a one sided IH, maybe with Prussia or Austria. We could play the whole war or just a singlke battle - I like both. I think this depends mainly in the interest of the operator and on how deep is his knowledge about this part of history and about military issues.
