This product, if the detailed instructions are followed carefully, will give you a good quality gaming screen. The shelves in the back side for the GM to store minis and the like have me the most excited, although the general look can add a lot of a gaming experience.
The towers double as dice rollers, which is not something that particularly excites me and does take the most work to accomplish, but it is one of the fun features of the product.
There are some downsides to consider, some of the instructions and markings are incorrect. It doesn't take much to figure out how to assemble things correctly, but it can still be a bit frustrating. More frustrating is that when it was all said and done not all of the seams were flush and there was some bending/warping of the castle walls.
Beyond that, if you're willing to print what must have been around 100 sheets or cardstock in color and put in the hours of work to get it together it is a fun project. It probably would have been good for me to do something simpler as my first project of this sort, but it was fun all along the way.
