Wanting more D&D games is an entirely different thing from wanting more games exactly like BG3.
I think we want the same thing 🙂 This is where the OGL discussion come in. I don't want to deny the people who like BG3 model to be denied their game but I don't want it to be the only model. I want dozens and dozens of games. Let a thousand flowers bloom.
It think you are saying you are concerned that BG3 can be like the Starbucks that drives all the indie coffee shops out of business? If so, that's a very bad thing, but I don't think that's inevitable - yet.
Part of the reaction against the OGL is a flurry of activity on the part of small devs to come up with DnD variants that aren't tied to WotC. Which would be sad - because Faerun is the world I like - but this looks like a classic case of the pattern identified by Princess Leia: the tighter your grip, the more slip through your fingers. One of two things are likely to come out of this - 1. either we will get lots of RPG games from small devs or 2. WotC will be forced to reverse course.
And they've done it before - WotC was forced to shelve 4e
