[color:"orange"] I thought it'd be easier on a 2D background? [/color]
No it is not .. reason the countryside layout would have to be totally created in 2 D without the benefit of 3D tiles as per NWN, take Baldur's Gate for instance, the BGTeam spent near to a year creating a small mod called "Dark side of the Swordcoast" and that was all done with member created tools, and ofcourse the "Infinity" engine which was fairly flexible.
So yeah when DD2 comes out in 3D it may be more possible to get a toolset, but once again it will depend a lot on the flexibilty of the Game Engine <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
