Right, but you have to remember that URDC is "GAME" and NoLimit Coaster is a "simulator." You also have to keep in mind that URDC is targetted for the younger crowd, 7-15 year olds or so I guess. That's Disney's job, entertain the kids [;)] and NoLimits Coaster was built to be more complex and interactive, well interactive in a way that you would have to think more and strategize more since you have basically all the freedom to do anything in the game rather than DC where u get a few premade segments and u play connect the pieces and build a nice layout. People take NL in a much more serious way. People do deduct for g's on fantasy though some of us give more flex in the g's field. Smoothness like u said is a must for both realistic/fantasy tracks.
