Another thing to add to my list of dream mods...

I would not wish to reopen the scale issue, which caused so much grief a while back. That said, I believe your day length would work well. You do imply, as I read it, that, historically, little night combat took place during WWII. I cannot comment on the Eastern Front, but a good deal of night action took place elsewhere. It may well be true that tank action was very limited, but that is not so with infantry activity.
