Vision is a Danish role playing system, which was constantly enhanced during the 1990s.
The game initially had two main components - a fantasy-genre implementation called Witchdom, and a dark-future-genre implementation called Fusion. Witchdom eventually was abandoned, though Fusion evolved into the commercial game Fusion.
Vision was primarily developed by Palle Schmidt and Malik Hyltoft.
Scenarios for Vision were run at several major conventions in 1992, 1993, and 1996. The rules, as a core system, have apparently never been formally published.
