Official Site: Dungeons & Dragons Online: Stormreach

Since March I've put in more hours than is healthy combining a big dose of nostalgia with a heady mixture of high-tech wizardry. Dungeons & Dragons Online: Stormreach is a massively-multiplayer online role-playing game (MMORPG) based on the iconic paper and pencil (PNP) Dungeons & Dragons game and recent game background material from Wizards of the Coast.
