yeah i always been the opposite benny, i would build the set and have it sitting on the shelf, and then rip it apart just cause i wanted the pieces off it to make something else

on that one site bricklink, theres a section where people make their own plans for stuff and you can find what you wanna build and go to town...you might be able to find a drawbridge or something in there. Theres even a program that is more like a 3d plan set so it looks just like the authentic lego direction sets
