Even if said polished D&D games are great, how many of them do they make per year? 1/8? 1/5?

Even if you add the non design-by-commitee immersive games that are not quite rpgs, you end with maybe 2 titles per year.

That's not always enough, and then you go and snatch the Avernum series and whatever promises to be similar.

Btw there was another indie company that promised to go the same way: https://basiliskgames.com/

They seem to have got snagged into an ambitious engine change though. And nothing's come out of there in many years.
