i fast travel because everything that breathes wants me dead and will chase me to the end of the world if i try to escape, if they change that then i just might ditch fast travel
I think they've said it's different this time round - IIRC they've mentioned that animals may be territorial, or if wolves have caught some prey, they'll stay and eat/guard that rather than go after you. I believe it's been said that giants won't necessarily attack you either. :thumbsup:
It was also mentioned in OXM that "you can engage a dragon whenever you see one simply by pelting it as it flies past, but you'd better make sure you're ready for the fight", which suggests that unless you make a nuisance of yourself, they might just leave you alone and go about their business.
[Double Edit] Found another quote:
"Rather than initiating a Benny Hill-style chase every time you wander near the local wildlife, many of the creatures will simply ignore you unless you give them reason to attack."
