well after reading all of this, i thought i would put in my two shinny pennies
First it is very nice to see Mongoose stretching their lil paws and producing so much historical stuff. I think for a while some people (SHort sighted) thought you were a one horse show (scifi/fantasy).
Im glad you are having a crack at WW2
My thoughts on what and when are quite simple, although a few people on this thread say no to Normandie and Russa, I think It is essentual to mongoose as a company to do exactly that, because that has proven to be where the market is. I know a lot of you would say thats just becuase no-one has gone for other theaters before.
Initially it should be normandie and russa, but then within a month..say..another theater...the problem with a lot of the earlier campaigns is that it involved the germans racing past enemy Walls in lots of bloomin tanks (who saw that coming), not a lot of scope for 'schirmish'.
So to conclude secondry theaters I would suggest (In no particular order)
Scandinavian (all of the battles discussed here)
African
And the long range SAS raids
Burma
Italy
French resistance and british SOE raids, during occupation and of course during the D day build up.
Dutch resistance, Scandinavian resistance
Crete
The japanese invasion of the pacific, and the Allies counter attack (as descussed here)
And a multitude of raids by paras, commandos and special forces.
Finally if you have time and want to indulge me and probably a few others, the potential invasion of britain with the 'dads army' home guard and demorolised Dunkirk vets (This could be a humourous addition) theres a chance here to have a rather funny WW2 game
