When I was a kid, we played Dungeons and Dragons in the 5th grade. It was fun, but so complex that we had to cheat to make it more interesting. Soon afterward, I decided that riding my BMX bike was more fun and didn't do so much gaming.
I did keep one relic of these days, it is a book called the Monster Manual and it describes all sort of different monsters. Someone sent in this carving of the monster called "The Beholder". I am unsure what it is, but it looks spooky.
I wonder if the monster manual is worth anything on E-bay. Just because something is old, doesn't mean that it is valuable, though.
