I don't have any half-dragons in my campaign for two reasons:
1) It makes no sense to me in my human-elf-orc genetics idea, which seems to be a bit like the guy with the orcblood/elfblood ideas.
2) It doesn't do anything for me mythologically or coolness-wise, and it doesn't fit my game. It seems "gamey" rather than a natural fit for my view of the D&D world, which is Greyhawk with a minor in Tolkien and a minor in my being a history/poli sci double major. Fantasy is cool, but it needs to be fantasy that works within its own logical constraints. Half-dragons are one step too far for me.
I also don't have half-ogres, though I'd use uruk-hai if I had good stats for them and story reason for them to be around. Orogs (half-ogre/half-orc) might fit for uruk-hai.
I also don't have saurians, or any other lizard-humanoid types except the traditional -- lizardmen, trogs, bullywugs, and maybe a few more I've forgotten.
I do, however, have and like mongrelmen. I don't have an explanation for them, but I suppose if someone researched it, I'd blame magic, which would make sense since the main place they occur in my campaign is in a Star Cairn, on a magic ley line in Greyhawk.
