Way i see it is its very early in development, so they probably had to script some of it so all of us wouldn't be complaining that we haven't been shown anything good. Plus the main selling point of this game is the dragons, so i doubt they will want to make them look really amazing only for them to turn out to be really buggy and lame on release day. So im guessing the fights will play out like that, even if some of it was scripted. The stuff about sprinting and all that has pretty much been covered on here already, but i dont think the edge detection would be hard to put in. I was playing assassins creed 2 earlier and when you run to the edge of something on there he plays an animation to stop himself, or runs off, turns and grabs the ledge (has anything along the lines of climbing been confirmed?). so it could work like:
- if your walking he stops at the edge, giving you the opportunity to jump off if you want but also stops you from walking off by accident.
- if your running it will play the stopping at the edge animation or you will fall and grab the edge.
- and if your sprinting he will just plain jump off, which could make some nice platforming sections. plus lets face it, if your sprinting away from a dragon you would probably take a leap of faith anyway.
so yeah ill stop rambling now
oh and just for the record, i am in no way saying i want skyrim to be the next assassins creed, all im saying is there are some interesting mechanics there that could work in the world of elder scrolls.
