El Dorado Gate is console gaming's first serial RPG series, where each Dreamcast GD-ROM contains 3 seperate (though interrelated) adventures, each telling a story of one of the series' 12 characters. There's 7 volumes in all, the first few introducing the characters whilst the later volumes flesh out how their stories are related, leading to the finale. Part of Capcom's experiment of serializing an RPG over a year with one part every other month.
