Indeed, they made plenty of mistakes, otherwise they would have won the war.

Therein lies the problem, because even if they somehow executed an absolutely perfect strategy they would not have won the war, not in the long run at least. I agree that Wolfenstein doesn’t glorify them since its reasoning for them winning is outlandish sci-fi technology, but a lot of media that assumes they could have won is glorifying, even if indirectly.

It should be noted that a lot of their blunders later in the war can be traced back to Hitler (or one of his sycophants) getting involved and overruling far more experienced Generals, many of whom were not party members. It could also be argued that the economy they set up, while impressive given the state of Germany post-WWI, was an entirely unsustainable war economy that relied very heavily on slave labor. That’s not to say they were completely incompetent, but they did vastly overestimate their own abilities and made many mistakes as a result.
