What I heard was a GM making a pitch saying that they wanted to run something inspired by GoT. Considering that Birthright has elves, I don't think that it's necessarily out of the ordinary for a player to propose playing an elf. If the GM initially used phrasing like "all human campaign" instead of "regular people," then they likely could have nipped this player's idea in the bud at the outset.You could. Why you would bother designing an entire game when you could just add a couple house-rules to an existing one is a question for the individual.
No, a guy who hears GoT and wants an Elf is not an asset.
