I want to address something some of you raise here about BG2 being a mainstream game. I don't think it's true.
The demographics have changed too, because I am pretty sure most of the PC gamers back in the day were pretty 'hardcore' or whatever you want to call it. But you know what's funny? If you look at https://web.archive.org/web/20030820032731/https://www.npd.com/press/releases/press_020207.htm which includes games from '99 it still basically says that there is a strong argument that BG2 is a niche game.
BG3 will be the first contender to try and become a mainstream game, but I doubt it because you're still gonna compete with COD / Among Us / Minecraft / Fortnite etc. those are actual mainstream games.
And where do Dragon Age, Mass Effect, and Witcher 3 fit on the "mainstream scale"?
