The Russians had a wide selection of tanks in 42 light to heavy tanks.(KV-1/2 being the most feared )
The Germans was limited with their selections in Stalingrad and the P4g in game was the best they had to offer in 42.
Well, it's not so bad.
Even though Germans had basically only Pz III/IV, with the odd assault cannon in it (like the already mentioned SiG-33B) versus Russian KV-1/2, T-34 and T-60/70, remember that Panzers were still available in two versions - long and short barreled.
So, like I said, there's enough to chose from on German side... and if that's enough, you could even drop in a Pz II, but not sure if anyone would want to drive that
While the Tiger was a great tank it was never made in enough numbers to effect the war(and wasn't in Stalingrad). And the Panther was again a great tank but by the time they got it into production the Russians was pumping out T-34/85's and IS-2 tanks in far greater numbers.German advantage was in crew training and radio equipment.
On the eastern front the Germans never quite wrestled tank supremacy away from the Red Army.
While I agree that Germans never had tank supremacy on eastern front (or on any front to be honest, with maybe invasion on Poland being the only exception) and that their advantage was in crew training, radio equipment and tactics, I can't agree that IS-2 was produced in FAR greater numbers. Just like ~2300 were produced until the end of the war, which is about as much as the production rates of both Tiger models, and like 3 times less than what Panther was produced. It was the cheap T-34 production that made all the difference (just like Sherman's on the western front).
Oh god, I want the KV2. That has to be one of the coolest looking tanks I've ever seen.
And now imagine that the turret has a second MG, shooting backwards. And it's manned by an AI aimbot. Would make any game the tank would show up a nightmare for the infantry
In which, I won't be surprised if the P3 that Germany is going to get will be the one with the L/60, which was the one that was said to be able to penetrate the T34, frontally.
Don't think it could penetrate T-34's frontal armour, only maybe when using some fancy HEAT or tungsten-core ammo. Though, I have to agree that a KV-1 would be a better choice for a new Russian tank - since it has the same main gun as T-34, don't think that would be game breaking at all. Adding in KV-2 though, would be a bit too much I think.
