Winter Operations - Kharkov '43: Tiller Operational Campaigns Tournament No 2

[HMCS Rosthern]

We have 11 entrants where I can find 7 common games. They are PzC 01 Smolensk '41, PzC 03 Kharkov '42, PzC 05 Bulge '44, PzC 15 Stalingrad '42, PzC 16 Minsk '44, PzC 19 Kharkov 43, PzC 24 Scheldt '44. FWWC and MC are not in this tournament. 



There are 3 other entrants that own about half the games the others do, akilpio, mersh, and nim8or, and I can not find a common game amongst the 3 entrants plus the above 11 entrants - to make a total of 14 entrants. Taking one of the entrants  to make 12 entrants it works out this way. akilpio (makes 3 common games PzC 01 Smolensk '41, PzC 19 Kharkov 43, PzC 24 Scheldt '44), Mersh (makes 2 common games PzC 15 Stalingrad '42, PzC 24 Scheldt '44), nim8or (makes 2 common games PzC 01 Smolensk '41, PzC 05 Bulge '44). 

So reluctantly, I am going to have to drop Mersh and nim8or from the tournament, unless they want to purchase some titles (A tough ask just to enter a tournament). 

The tournament is open for additional entrants until September 30, 2359PDT.

Asking not to cause you any trouble, but only to see if there is some way to get everyone that wants to play into your tournament.  Is there some minimum number of common games each participant must have in common with all other players?  Is it just 1 title common to all entrants?   Or three or five?

The issue is balancing out the scenarios over 6 rounds. By balancing I have to consider:
1. Giving the entrants equal opportunity on attack and on defense. E.g. If Sheldt '44 were the only title, there are very few appropriately sized scenarios putting Axis on the attack (first player).
2. It would not be fair if, for example, all the scenarios gave the Allies the advantage. As such I have to use the theBlitz.club scenario database and my own experience in making sure the selected scenarios do not give one team an advantage.
3. The more titles in scope the easier it is to select scenarios to meet the criteria. If it's one title, then all entrants without the title could not participate. On the other hand, for example, if Kharkov '43 were the title, due to the history of the campaign (initial Russian offence followed by an Axis counter attack) I could put together a tournament to meet some of the criteria. 
4. I don't want to rely on a mirrored tournament to remediate the issues.

This has been a learning experience for me, and in some ways with the initial tournament design I have painted myself into a corner. I'd welcome any ideas to let everyone play, except mirroring. Also, I apologize for any disappointment.
