I'd like to see a 20 minutes into the future setting, if possible.
An interesting idea, though that does mean that I loose my historical setting from which I could draw units from.
Lack of fossil fuels or some other resource(s)
I kind of intend to make this happen due to enemy ruining your supply chains.
No developed chemistry (meaning no smokeless powder and high quality explosives)
Not sure about the effect of this on the game. The lack of high quality explosives would make armor more important, while cannons belching smoke might shroud the battlefield in smoke, thus requiring even more munitions to be thrown around.
Magic included
That would mean lots of more work for me, as I'd have to set up a magic system. Otherwise it justs becomes rule of cool, people voting the most silly projects in, because magic can solve it anyway.
Not humans and\or more than one race in the world
Would this make a difference?
Different G\Atmosphere world making artillery and aviation behave differently
Difference would be fairly small I believe. Just ranges of artillery changing and the size of aircraft, as well as the viability of airships.
If nothing from above, I'd love to see 1890 instead of 1920 year tech start.
What would the main differences be. I mean, rather than being a backward nation catching up to the new trends in planes, submarines and such, you would be developing them, but nothing that serious. It's not like I was that accurate with the time line in the first game.
And consider turns being shorter than one year
Considering. However, the problem will remain that in order to keep the design part of the game interesting, battles will be compressed and wars will take a bloody long time.
Consider a hard cap on number of projects developed.
I dunno, the soft cap in the original game functioned quite well, by restricting it to a couple of teams you had.
Consider making infantry squad a single unit like a tank, treating individual weapons as engine\armor\main armament\secondary armament.
Considering
