I was in his live stream. Not being a D&D guy, and knowing how things worked, was a real frustration for him.
Things like the spell description of Magic missile. No where does it state that is an always hit spell. He asked us where do you see that? Just trust us, we know this stuff by heart. But for non D&D people, even 5E is a complicated system to learn.
Brian Davion "BG1 and 2 didn't have much of a tutorial eaither." While true, that was a time when the game came with a thick manual to explain things. And a very nice cloth map that is still on my wall today

There are lost of people whining about the $60 (Have you been on the Steam forum?) Dos2 you could by in at $27.00 on kickstarter
"Pledge US$ 27 or more
Bye Bye Birdy Offer
Divinity: Original Sin 2 as a digital download for PC, available from Steam with Alpha and Beta access included, or DRM-free from GOG.com. Also comes with a Digital Game Manual, a 'Backer' Forum Badge, and behind-the-scenes footage."
I'm not saying this should be the case on this game but it is what it was.
"He spent half of the review basically crying that he paid the game 60 dollars" Little hyperbolic Tuco?
If you watch the whole video it is overwhelmingly positive, and his criticisms are completely valid. It's not like he doesn't know what an early access game is.
