Trying to remember the name of a game I played a couple of times, probably in the 1984-1990 timeframe. It would have been on either CompuServe or GEnie - I don't think it was on a BBS, as I rarely dialed into those, but I suppose there's a small chance I played this game on one of my rare BBS calls.
It was a multiplayer game where you played a spellcaster. You chose from one of several specializations - I remember playing a Summoner who summoned monsters to attack the other players. I seem to recall that the view was similar to Rogue-type games. We were in a maze or walls or rooms. But I don't remember now whether there were simple graphics or whether it was purely text.
