the baffling decision to purposely make an unrealistic game while spending so much time making the playing pieces so realistic.Its like spending hours hand carving amazing chess pieces only to play draughts with them.
This is where I disagree and I think you’re not understanding the scale of the issue. Realism in the way you are describing cannot exist because there are too many missing pieces to support it, time travellers are the least of the problem.
To use your chess analogy, War Thunder having tanks and aircraft can at best be likened to a game of chess where only the Knight and The Queen are on the battlefield.
(Knights being tanks, Queen being Aircraft and the pawns, bishop, rook, king representing the infantry, politics, fortifications and logistics that form the majority of war)
To my perspective, war thunder being a vehicle sim, is such a limited perspective of war as a whole, that attempting to create ‘realictic encounters’ between vehicles of specific era’s is completely redundant.
At all Battle rating regardless of era, the battle are highly mobile and energetic, the tanks are fighting like infantry or mecha (like mechwarrior or armored core for example). Even the famous blitzkrieg was a static battle compared to what is playing out in ground battles in war thunder. WW2 vehicles are driving around and shooting as if it were the battle of 73 easting.
The most crucial piece of any genuine tank battle is missing from war thunder and that is the fixed/towed anti tank gun. Without this there is no point even considering realism as an option.
In short, none of the tanks in game are behaving anything like tanks in reality in my perspective is not and never has been the capacity in game to accommodate realsitic vehicle behaviour. I think Gaijin has done well to understand this and to allow vehicles to be sorted by player competancy and not by performance or Era.
Tank combat is short, terrifying and frantic exchanges of fire where brave and professional tankers maintain their compsure under fire long enough to survive. In between these brief engagements are long pauses characterised by preparation, tension and boredom.
The battlefields in reality were rarely what could be considered a fair or even match.
