In recent years our group has played D&D, Pathfinder, Runequest and Call of Cthulhu.
Besides those the other games I've refereed long campaigns for are Pendragon and Vampire the Masquerade.
I'd say my RPGing is about 75% fantasy, horror coming 2nd, and SF being well-behind.
Yeah, I think my gaming group way back when was similar. Probably 2/3rds was D&D, then some
Champions, then maybe 10% was a bunch of other things. Chaosium's
Call of Cthulhu. TSR's
Boot Hill. I think we tried Fantasy Games Unlimited's
Bushido after seeing
Seven Samurai for the first time. Except for a brief foray into TSR's
Gamma World, we didn't play much sci-fi either. I always kind of wanted to, but it never really happened. This was before so many of the great space opera tv shows came out, so maybe we were just stumped for inspiration. We were watching
ST: TNG at the time, but
DS-9 hadn't come out yet. Then you had
Babylon-5, Farscape, BSG 2004 and
The Expanse, so there's a ton of material out there now.
Our group mostly plays D&D 3.5/Pathfinder or Star Wars Saga Edition, but we've also played Palladium's Heroes Unlimited and a couple of others over the years.
Gosh, I'd forgotten about Palladium games. I don't remember ever playing
Heroes, but we tried
Beyond the Supernatural. I think we were interested in another horror game after Chaosium's
Cthulhu. And I think we incorporated elements of
TMNT because I remember playing a character who was some kind of "man & animal" hybrid.
