Dungeons & Dragons Collection is a 1999 game for the Sega Saturn. It combines ports of two Capcom arcade beat-'em-ups that tie into the Dungeons & Dragons franchise: Dungeons & Dragons: Shadow Over Mystara (1996) and Dungeons & Dragons: Tower of Doom (1993). Shadow over Mystara requires the use of a 4MB RAM cartridge while Tower of Doom doesn't, as it's an older conversion which had been planned to be released as a stand-alone product in 1996.
