Well theire could be a standard barrier to guide the player (I don't need no guide tho) like:
Ow crap the bridge is withdraw, I will have to find the bridgekeeper. Ow what luck he's just been kidnapped by the blank ring, well I guess I'll go save him as part of the main quest (louwsy bridgekeeper getting him self caught by the black ring).
But once the bridge is fixed you can thravel to the new area but also back to finish old quests or to solve a new quest foud in the new area.
Like:
Hey I found that special potion that guy on the other side of the river was searching for, well might as well go back and give it to em.
Also I will be checking if the new 3D world is exactly the same as the <img src="/ubbthreads/images/graemlins/div.gif" alt="" /> world as they are the same (+/- 20 years) So that means caves, rivers, ruins, castles would still be at the same location. otherwise there are plot hole. Hey were did stormfist castle go to (activates plotmachine) <img src="/ubbthreads/images/graemlins/silly.gif" alt="" />
