Ravensword is said to have an open environment with a main quest line that will take anywhere from 3 to 6 hours to complete, along with a hefty amount of side quests to also keep you occupied. What I'll be interested in seeing is how extensive the side quests in Ravensword are, because I had much more fun just fooling around in the open game world of Oblivion than playing the comparatively short main quest line.

Take a look at these screen shots and concept art, also the developers are collecting ideas for the game in their thread on our forums. If you'd like to see something added or have other suggestions, don't hesitate to post them.
