Everything is looking simply marvelous, loving that French infantryman!
On the issue of including certain nations (e.g. America, Australia, Canada, etc.) it doesn't really make sense to have them included as seperate factions... or even regiments for that matter. There's not an awful lot of variation in their uniforms (compared to Britain) and besides, it sounds like the devs would rather get a playable version out with the basic classes than spend time creating dozens of unique
regiments (at least for the initial release).
Which seems to me to be the best way to go about it, we're all itching for some trench warfare already, are we not?
So instead of pestering the devs to divert their time and effort towards including your country, simply reserve a regiment and use the default infantry class...
Oh and I'm Canadian btw
