I've been saying for a long while now that the D:OS fanbase does not have a significant overlap with the BG fanbase, so the D:OS and PoE demographics having little overlap makes complete sense to me. This is why I also say that Larian making BG3 primarily for the D:OS fanbase rather than for the BG fanbase does not make sense. And yes, the game IS being made primarily for the D:OS fanbase.
