You do realize that when you say that, you need to back it up with something, right?
Thought I did. Clearly we have different perceptions.
Really? Please provide me with the original Deities and Demigods entries for Mystra, Lathander, Cyric, Ao, Mask, and others.
But this very carefully selected excerpt only serves to prove my point.
Tyr = Norse god Tyr.
Meilikki = Finnish goddess Meilikki
Tymora = Greek/Roman goddess Tyche
Akadi = Moorcock deity Lassa
Loviatar = Finnish goddes Loviatar
Oghma = Celtic hero-deity Oghma
Kossuth = Moorcock deity Kakatal
Sune = Greek deity Aphrodite
Silvanus = Celtic diety Silvanus
Ilmater = Leiber diety Issek of the Jug
Gruumbar = Moorcock deity Grome
And so on and so forth.
It's a bottom up pantheon composed of deities chosen out of the Deities and Demigods manual. I'm not sure thats even contriversial; it's a matter of historical record.
So, where do dieties like Mystra and Mask come from? They enter the pantheon because after Ed chooses his favorite 'god of Paladins', 'god of Druids', and 'god of Rangers' from the Deities and Demigods, he finds he lacks a 'god of Theives' and 'god of Magic-Users' with the simple portfolio he wants for each of his 'god of <class X>' buckets. So he creates deities like
Mystra to be the 'god of Magic' (which is kinda like being 'the god of Physics') and Mask to be the 'god of theives'.
Which is something the Greyhawk deities have yet to do.
Earlier you claimed the problem was I wasn't very familiar with the FR deities. Here I return the accusation to you.
So you think the Greyhawk gods were better developed because Heironeous and Hextor are brothers, is that it?
As a gross oversimplification, yes, yes I do. Although, once again, you keep substituting 'developed' (your point) for 'concieved' (my point). I freely admit much detail has been lavished on the Forgotten Realms. It has been my point all along that this has never served to make the setting particularly interesting.
But, back to the topic of family, it's that you can write sentences about the Greyhawk deities like:
"Berna is the third child of the serpent god Meyanok, transformed by the power of Xanag from a spirit of hate to one of passion. Her older siblings are Vara and Damaran. Her grandmother is Breeka and her great-grandmother is the sun goddess Nola, who was awakened by the creator god Uvot."
Which novel or sourcebook really outlined the multiple facets of Xerbo?
Here I must confess that if the multitude FR novels make the FR deities seem interesting, that I would have completely missed out on that. Sadly (or not), this situation is likely to persist and my opinion remain unchanged, because the few FR novels that were thrust upon me by eager friends proved to be almost wholly disappointing and in some cases rank with the worst fantasy fiction I've ever read. If it is your opinion that the FR novels make the FR deities and pantheon seem truly deep and interesting, then I can only take your word for it.
Beyond his portfolio, who is Phyton, really?
The incarnation of a very troubling philosophical question that remains throughly relevant to modern life, namely, "If nature is cruel and indifferent to man, is man's domination over nature a good thing, or is it merely destruction given a pretty face?" I'll leave it to the archivists and lore masters to dig up any instances of that being detailed in published works, but right off the bat reading his description I'd find him more interesting to include in my campaign world than any FR deity.
