I don�t think BG3 is going to inspire many other studios to make many similar games. The really exceptional aspects of BG3: Visuals, Cinematics, and Voice Acting are not unique to CRPGs.

I assume that BG3 ended up being a commercial �success�, in terms of earning more money than they spent in development. However, I have no idea of what the return on investment is likely to be relative to other games. Based on the fact that Larian pushed the game out in an unfinished state indicates that they were either struggling financially and/or worried that they were not going to be able to recoup their development costs. I wouldn�t be surprised if their game development expenses went way beyond what they planned for.
