The back and forth on twitter/bluesky over this topic was pretty wide ranging, and size/cost definitely was a topic discussed. And besides a lot of the “quality” of BG3 was the fact that it supported endless paths through the game, something which requires a lot of development effort.
Well that’s probably a bit predictable given what community this is. But I really think the pricing is way out of line with what your average person is willing to pay and it only serves to make the physical media more niche.
