TBH I honestly don't think that any other war could get so many people to play the game than the WW2.

People are interested in WW1 right now because of Battlefield. And the image Battlefield showed was more WW2 in the locations of WW1.



WW2 is the perfect setting. 2 Main rivals (Axis and Allies) that are somehow equal in terms of strength. "Cool" units, tanks that are not invincible or way too weak (like modern tanks)...



Also stuff like Vietnam, Korea etc. doesn't fit to the franchise. You cannot control other units than vehicles and inf in CoH (which I think is pretty good). How would you add airplane/helicopter control to the game without fucking it up?



Also think about balance. In a Vietnam setting it would be: Vietnam player: Hide inside buildings, US player: Napalm everything. These are all GUERILLA WARS! That means a war where 1 side is extremely weaker than the other but manages to stay in the conflict because of urban tactics and stuff. Not fitting for CoH if you ask me. It would be a CoH that relied purely on cheese tactics for the Vietnamese player, lol.



I voted for Normandy, but my dream CoH3 would include The Western Front, The Eastern Front and Afrika.

3 Allied Factions (US, UK, Sov) vs 3 Germans (Ostheer, Westheer, Afrikakorps).



Also make a nice campaign that also shows the German point of view. CoH2 campaign absolutely sucked balls IMO. I never finished it because it was so boring and uninteresting. You could have 3 'small campaigns' with 10 missions each, 5 for both sides. UK vs Afrikacorps, USF vs Westheer, Sov vs Ostheer.
