For me, the most interesting point was the short mention of open sourcing Factorio (around 2:40). Kovarex seems to be very much open to the idea, he mentions that (as an approximation) maybe two years after the DLC after things calm down ...
Is anyone even still buying Factorio? I was under the impression anybody who could possibly be interested in it already owns it. It's also quite cheap.
The DLC launches next month, so it has seen a surge of renewed interest. And once the DLC lands, it’ll likely get a surge of new players from being on the store page again.
