In my own opinion, the Forgotten Realms is the coolest place in the whole AD&D gaming system. This is not to say that you should automatically choose this realm of fantasy for your campaign setting, however.

    The Realms is the most popular, most detailed fantasy campaign world ever created! Here gods walk the earth, and fantastic armies clash. Visitors explore a vast frontier filled with fascinating folk, from bold heroes and whimisical characters to shadowy villians and clandestine socities. This is the home of Elmister the sage, and Drizzt the dark elf- two heroes featured in TSR's best-selling FORGOTTEN REALMS novel line. No setting can match the grand scope of the FORGOTTEN REALMS campaign world.

    If its action and adventure you want, look no further. The Realms also supply a good opportunity for role-playing with famous, and infamous, non-player characters (NPC).
