So in simple words, more story, make it cheap and fast to produce story so that you can make more of it.
What? How are they supposed to do this?
"Thats why i think cost effective ways to add side stories and extend mainstory and multiple possible routes for these is much more important than cutscenes and cinematics which early acces has quite a lot."
Less cutscenes, more content. That's what he's saying.
I have to say it reminds me of people thinking 9 women will get you a child within a month.
Jokes aside -> Yes more is better. We'll see, they said BG3 is going to be 3 times larger than DOS2 and that makes a lot of content to begin with. Especially if you're a completionist.
