Left out countries

Just as a sidelight, I would be glad to buy a game exactly like the enhanced version of SPWW2 with a WW1 timeframe included.

Would others? If not, then I agree it's a waste of time. If you have a sufficient fan base willing to pay $45 for a download of just such a game, say SPWW2 version 2 with WW1 included then have at it.
Post a quick vote on it?!

Also, and I know I'll get harpooned for saying so, but it doesn't have to be a perfect WW1 historical OOB for me - it's all relative and close is good even if the exact composition of a New Zealand rifle unit isn't known. I'm sure the Kiwi's will chime in to fix it.
