<Easy Red 2
You can play Easy Red 2 for almost the entire of ww2 as any side you want. But... doesn't has any storyline, it's just maps, and can get very repetitive, given how if you play anything else but a tonk and minmax the enemy kills you'll lose. And sometimes is impossible or almost impossible to win as certain sides. But still can be fun. This said, games like enlisted, hell let loose and squad 44 (formerly post scriptum) you can play as the axis minors too, I liked playing italians in enlisted, sadly the game is a f2p grindfest.
<Red Orchestra 2
Has german campaign, but they removed the SP from editions after 2014, so when on the high seas, check the year I guess. I haven't played this one, but it seems to be the multiplayer mode with bots and some cool narrations at the beginning of the level. If you want something more autistic, there is Iron Front: Digital War Edition which is like an Arma 2 standalone game or something and you can play as the germans, but is not technically a campaign.
<Call of Duty 2
Has a mod called Call of Duty 2: Waffen SS Edition, also you have the Back2Fronts that adds missions for every side, including germans. Not axis related, but I suggest the spanish civil war mod for cod2
