While sales numbers are important for the company to keep up development or do new development, these numbers to me are not the big factor. BG3 has changed the conversation when it comes to CRPGs and the RPG genre in general.
The last time we saw a game cross genre and work it's way into the world outside of gaming was Skyrim. Skyrim brought an extra spark to the world of RPGs and generated a lot of interest in the genre outside of those that typically play. BG3 is having a very similar impact and goes further as it is creating stir in who a game should be made and released.
BG3 was not and is not perfect, there were issues but compared to most launches it was VERY clean. Additionally Larian made a claim that has created some noise, NO EXTRA COSTS. Thats a big deal, especially when you have Cyberpunk coming back to the well so long after launch and Starfield already discussing a launch window for DLC.
Larian has a window right now it could capitalize on. Announce a new adventure. A full campaign that would be an alternative campaign for BG3. Use the existing engine and make at the start of the game you choose an Adventure based on which you want to play. This is not DLC or micro transaction, it is in essence another game without the need for full development or cost. THIS to me is the future of RPGs. You keep adding new adventures, maybe do engine updates. You build the gamer a library of adventures for them to go back to again and again.
