Yes i don’t want technology to be too elaborate. This is easier. The more you buy the closer you get to better models.
Each nation could have different targets
This is the path to national unit values and the next generation of games of which is support but the lack of pieces was always in the way.
And you can keep the D6
based on my proposal, what would the Soviet tank lineup/stats be?
For Soviet tanks:
T-26 ( light) 2-2-1-5 ( start with these, after you buy X number you can start buying next model) ( note these can also be used by many neutrals as their primary tank too)
T-34 (medium) 3-3-2-5 ( after you buy y number you can start buying next model)
IS-1 series( late) 3-3-2-6 ( last model possible)
Plus:
SU-76 3-2-2-8 ( attacks at 4 if fighting other tanks can start buying them on turn X)
SU-100 3-3-2-8 ( after you bought Z amount of choice 1, you can start buying these ,attacks at 4 if fighting other tanks)
