vometia, yes, you are right. There are exaggerations but remember that Germany din't had much materiel available and had a lot of slave labor to use on Europe but IMO they lost the war much more because their leader stopped listening to his Generals than by other factors, anyway, my point is just that some times, balance goes against other things, like variety, immersion, consistency and in some times, world building. Look to War Thunder. Between nerfing planes like Me 262 and making the Me 262 to have less firepower, climbing and speed and be eqqual to same era planes, put then in a 0,001% change of getting on a lootbox or make the plane fight against cold war era planes, they decided by the last option. But on a SP game, you can make an unbalanced game and will be no problem.... Adolf Gallad said
". I would at this moment rather have one Me 262 in action rather than five Bf 109s." and note that BF 109 was not an bad plane for his era.
