What I'd like to see, is a single Dragon entry in a DIY style. Choose the different paramters (or roll on the tables), and when you're done, you've got the unique dragon of your dreams - and a nightmare for your party. What paramters might a dragon have?
Size: is he small as a dog, bigger than a horse, or a sleeping mountain?
Body: serpentine or stocky?
Skin: scaly, turtle shell or even iron?
Limbs: two legs, four legs, or even more?
Wings: has he got none, two bat-like or something completely different?
Head: is it like a serpent, a crocodile, a lion or some differen beast?
Breath: is it a toxic cloud, a huge firewall or just stinky?
Anything else: beholder eyes, petrifying head, tentacles under it's mouth? Why not?
Would you like to see dragons too in DCC RPG? How do you imagine them?
