When it comes to creating scenarios and wanting to test your skills, then you will enjoy using the creation utility that comes along with the game. I'm not a mod maker, but I tried my hand at using a simple tutorial, and must state that I understood the instructions. I enjoyed messing around with it and the DS site provides a "university" where you can teach yourself to use the tool set. I enjoyed playing the expansion as much as I did playing the original game, and if you are one of the many fans of Dungeon Siege, then I think you'll like this as well.
