“Choose” isn’t really an accurate term to use in your comment though, is it? Obviously high-realism AAA game graphics are going to come with a high budget outside the realm of possibility for the average indie dev, unless they have some super talented people with a passion for the project working for cheap.
A lot of us are willing to make this concession or adjust expectations for an experience that has great gameplay, soundtrack, story, etc. as easily as reading subtitles to enjoy a foreign film. The imagination can do plenty of the heavy lifting.
Larian is an unusual case. It’s indie but it’s huge. They aren’t funded by or marketing through a bigger publishing company so IMO that’s still indie. But they’re hundreds of people so not really small, and BG3 can by all means be considered a AAA game because the difference in quality and scale is indistinguishable from AAA published games.
