Ok. I'm just waiting for MG 3.5.3 release to put the Sci-Fi pack out, so this is kinda a holding pattern.
I draw all my own textures (parts of tile sets excepted)
I'm thinking cold war up to say 1980. After 1980 things get too powerful, and too familiar. There's a lot of interesting kit that is largely forgotten by peops who thing GW1 was how Cold war would have looked. So all real units although we can spice it up with some prototype/experimental types, but nothing that is completely made up or over the top,
And MG is easiest for me so no APCs/MICVs
Russia had the best tanks, well better than USA anyway. We can reduce this deficiency in USA by having MBT-70. What a lot of younger peops forget is that the reason the US introduced the incredibly expensive M1 Abrams, armed with a British, later German, gun, and defended by British armor, was because up until then the US tanks were decidedly weaker than Russian ones.
I thoughts for balancing are:
Soviets - best tanks, decent helicopters, good air defenses
USA - weaker tanks but generally best technology, excellent attack helicopters
Britain - excellent tanks, harrier jumpjet
Germany - excellent tanks, tank destroyers. weak helicopters but experimental jump jet
France - average in most regards, best anti-tank missiles, most units upgradable (common vehicle chassis)
Could also include, if someone made them:
Sweden - some interesting units but some gaps in unit classes
Japan - some cool kit but blossomed in 1980s so most too late?
Italy - um, I guess
China - kit was terrible back then, and mostly Soviet based so little uniqueness
Warsaw Pact state - variation on Soviet, some WP non-Soviet types
