Graviteam Tactics is supposedly the best tactical/real time WW2 game (take that, Battlefrontailures).
Unfortunately, it's a) a hardcore historical wargame that's b) made by Ukrainians.
That means that tutorialization is nearly non-existent and not exactly easy to understand.
So a few years ago, I learned the bare basics of the game on YouTube from Arch Warhammer.
He goes by Arch now because he shit the bed so hard being a reactionary dipshit that GW made him drop Warhammer from his title.
The tutorials helped, sure, but were delivered in the tone of a faux sophisticate that every jackass who ever bought a fedora tried to be.
