Gale Force Nine released/is releasing a tank-on-tank game set in an alternate history 1948, featuring experimental or hypothetical tanks and assault guns. The rules come in starter kits with tanks. However, i have access to 3d printed tanks, so I don't actually need the models, just the rules. I don't think they plan to sell the rules separately, at least not any time soon.
So, I was wondering if there were any other tank-on-tank games that either have tank stats for vehicles like the American T-28, or the German Maus. Failing that, are there any tank-on-tank games where you think it might be relatively easy to extrapolate stats?
The only current tank-on-tank games I know of right now are What a Tanker, and the relatively new Achtung! Panzer (though I have several older sets), but those are quite strongly tied to WWII.
Any recommendations?
