One thing maybe would be to not have the VAs saying which god your character worships? One of my characters is a half-elf and when he saw what happened on the nautiloid when you hit the "perfect" button he said something about Corellon. What if I don't worship him?
That is the problem (YMMV) with games replete with voice acting: the voice acting. When it comes to voiced NPCs, it takes quite a bit of time and budget to account for the beefy amount of backgrounds - religious or otherwise - in a well-established setting such as
The Forgotten Realms. Including demigods and non-Faerunian divine powers, I'd say there are
at least sixty gods worshiped in the Realms.
The original
Baldur's Gate games had an easier time with that sort of depth because most of the dialogue was written. The best we can hope for with Larian's offering is quality over quantity (i.e., fewer gods).
