I think BG3 will sell 10 million! I think it will sell at least as well as the Dragon Age games if not more.
I am not convinced. It is not my wish it sells less then 10 million. That said can I have seen many youtube lists of best upcoming games in 2023. Roughly 50% of them do not mention Baldurs Gate 3 like it would not be among best titles for 2023.
Another problem while I love the engine Unreal 5 kind of puts in shadow even BG3 graphics despite BG3 is good looking.
It is not only about your personal Early Access experience. Marketing is a thing as well. It will beat no doubt DOS2 sales, but DOS 2 sold like roughly lol 1 million. BG3 will perhaps sell several millions, but lets see if it can go up to 10 million and I have a feeling Hogwarts Legacy sales aka J.R Rowling woman hero is hard to beat. It has been silent now how Hogwarts Legacy sales currently go, but in 2 weeks it had sold over 12 million units.
