Yeah, I think Eladrin are rather unlikely, but I'd love to see how they go about the seasons thing.
We get a tiny taste of the seasonal thing in elven eye colors. It's a nice touch.
I think we should have a whole game about elves and just elves. All the different varieties! All the lore! Trips to the Feywild, Evermeet, Myth Drannor, Evereska!
Aaaand probably no one would buy it. sigh
I don't think so! It's never been done before, has it? If done right, it can make for a great game The closest thing I can think of is Kingdoms of Amalur, it is a little bit of a niche and unknown game but those who know it seem to love it.
