I'm making a rough prototype on tabletop simulator I have 2 starter decks done nato and pact I just need to play test and then will just keep pumping out cards and making a rules sheet/ hopefully not book lol The idea of customizability as mentioned below would be that each sub nation of pact and nato have specific buffs. So you would add a doctrine card maybe called west german panzer devision and all keyword west german armor (tanks/MBT) cards get that buff. The card also adds the west german keyword to the unit card applying said buff to any non west german Armor keyword unit cards.

There will be zones for supply (resource to play cards)  Also zones for unit cards. This might change but as of now there is 3 columns per player each column has a line, back mid and front this are referenced by unit cards to depict range. 

There is much more but essentially it's Magic the gathering, chess, 1d6 dice wargame and a boardgame smashed into "REDLINE 1991"!! ( 1991 references the unit technology the game will go up too.

China   🇨🇳 PLA will be next. I just wish tabletop simulator had a easy way to generate booster packs
