Well he's suppose to be big enough to actually eat Nirn. I hope we actually get to fight him and theres not some stupid relic that stops him in his tracks. I want a real boss fight for this one, platforming elements and all (if possible).
If done well, I predict he will be the most epic boss of all the games that've played.
But its size is only metaphorically (at least I think so), we have seen the avatar of Akatosh in Oblivion, but, it was only the Avatar. :toughninja:
Eh, most likely Shor will make an appearance to stop Alduin again, or we're trying to prevent him from awakening. Fighting a world sized dragon just doesn't seem possible...
I do not believe that we can not fight him, at least a bit would be interesting.
