It would depend on how high a level we can reach in the main game as to whether there would be an expansion.
If however, there is a second installment (expansion).
New classes
New races
New monsters
New graphic settings
New items
I am for the GM mode and Editor. As Swen says he has "Access to the Toy Box". I also want to play with the Toy Box.
If this story is done maybe they will get the Ebbreon license or perhaps the Spelljammer license.
At any rate I hope this is a success and continues into the future.
