Yeah you mean something like having a reinforcement and recruitment time bonus while gaining a morale and territorial pride (defense on core) boost? All tied to the amount of brigade the Red Army has on a daily basis?
In DI:G I faced a Soviet Army that was almost destroyed in the first few weeks of Barbarossa and then it started building infantry divisions in 8 days and armored divisions in 21 while their morale and reinforcement were almost instantly regained with all those fresh troops. If the winter and the mud didn't hit me so hard I could have resist more but I didn't refit the russian railways in time and that killed my (newbie) Barbarossa organization. ^^
I don't know how you will feel it, but I really enjoyed making (and seeing) this happen.
I would feel GREAT!!!!!!! Let's face it the that was the real epic land fight of the war. And it should feel epic. Win or lose it has to be a struggle. As said here and many other posts I like what ICE has tried to do. Yes come winter without clothes or railways my whole army was reduced to a shell. But the only time that ever happened was when I held back and didn't play to win during the summer.
