An interesting
role-playing game by
FASA, vaguely thematically connected with their later
Earthdawn game.
Shadowrun posits a great cycle of periods of increasing and decreasing magic...and it happens that one of the big ones hits near the beginning of the 21st century.
Consequently, the game involves a cross between cyberpunk and fantasy genres, and for the most part pulls off the mix rather well (despite some complaints by naysayers who prefer their cyberpunk "pure").
Shadowrun has spawned multiple novels, myriad sourcebooks (including some fan-made Internet versions), and even a Nintendo game.
