Really ? You can literally play Light Domain Cleric of Shar and when SH reveals shes a Sharrite, main char goes "or really, tell me about it, im tolerant !" same as when playing any other class.
I have played BG, BG2, expansions, enchanced editions, IWD, IWD2, NWN, NWN2 with exansions, than there is Pathfinder and Pillar of Eternity... And i the only effect of choosing diety is a buff to dieties favorite weapon. All else, meaningless. RP value zero, just character creation and some alligment limitations.
I dont remember selecting diety having ANY value to character generation in BGs and IWDs outside me reading about the diety to have a feeling of good or evil party. For this purpouse you can pretend you are Ilmathers or Tyrs or whatever.
