So some people (myself included) were annoyed by the face that none of the dragons had loot caves like Smog from LOTR.
But in future games i was thinking that perhaps in the MQ you would have too seek some sort of knowledge or a magical item from one of the dragons that escaped skyrim. You could fight him and he would be an uber boss. You could attempt to sneak in (that would be hard). Or you could do a quest or small questline for him and he would give you said item. He would also have a large amount of wealth and magic items in his lair.
I would like to see classic DnD dragons in future games. Would you?
Not sure I'd like the six-limbed DnD-style dragons showing up in TES. TES dragons have always been the two-legs-two-wings "wyvern" style, and adding the four-legged style would just seem like an out of place appeal to pop culture. Nothing of the sort has been mentioned before in lore, and it would feel like an unnecessary addition, undermining the style they originally wanted.
But I'd be all for cave-dwelling dragons with a hoard (http://imperial-library.info/content/recovering-soulgem). I was expecting to be able to find at least one non-hostile dragon lounging out in a Dwemer ruin (http://uesp.net/wiki/Skyrim:Vulthuryol).
