The worry for me is that other game devs see the success of BG3 and try to emulate it, thinking (perhaps not wrongly) that its success was due to the sexualisation of the story. It might be hard to find RPGs in the future that present a more balanced view of sex or just let us adventure in peace without all the dating rubbish.
The company spent a lot of resources to implement this additional content, which did not allow them to fix technical issues in the game in a timely manner, some companions are still not fully implemented (Minthara), so I hope that other companies will pay attention to this as well and not follow this trend after all.
