Advanced Dungeons & Dragons: Cloudy Mountain

Advanced Dungeons & Dragons is an Intellivision game; it was one of the first Advanced Dungeons & Dragons games to be licensed by TSR, Inc. It was later retitled to Advanced Dungeons & Dragons: Cloudy Mountain to distinguish it from the sequel, Advanced Dungeons & Dragons: Treasure of Tarmin. It is the first Intellivision cartridge to use more than 4K of ROM. (wikipedia.org)
