Gaming is fun, and fun is for everyone
I don't like the idea of dragons having created basically all of D&D and coming before everything else. Never been a huge fan if them in general. I prefer a more traditional deity-based cosmology, like Tolkien with Iluvatar, or Greyhawk and the Realms (both of which are similar). It'll be a lot easier to believe the dragon myth is just one interpretation when there's more than one interpretation.
Obviously just my preference.
I think Dragons should be responsible for exactly half of Dungeons & Dragons. The latter half.
