I can start:
Dungeons and Dragons
The only official Edition of D&D I've played is 4. It was fine. It gets more shit than it deserves.
No GURPS. No WoD except Two sessions of Changeling: The Lost.
Ayslyn those systems that keep coming up in conversation here or in other rpg places.
Traveler, Shadowrun, The One Ring, Rolemaster, any version of Werewolf, and any "new" WoD game.
Oh! And D&D 4th. I have the books, never played it. 🙂
Oh, if Traveller, One Ring (which I've never even heard of), or Rolemaster are 'common', then add them to my list too. Never played them, and I'm almost certainly never going to.
Azhrei_Vep I think Traveler is pretty common these days. TOR and RM I'll give you, even though RM has been out for ages upon ages. 🙂
D&D 2e or 4e, Traveler, anything World of Darkness, GURPS, anything Hero System, Pathfinder 2, Starfinder, FFG Star Wars.
Star Wars d20?
Oh wait. 5e D&D.
D&D 4th (and only 2 sessions of 5th). PbtA (any),White Wolf stuff (ok, I played 1 session of Vampire 1st ed, and 1 session of Mage 1st ed, but that's it).
I'm there's plenty of other "common" games I haven't played, but as mentioned, define common. 🙂
Hmmm... I would say, none of them, at least once....
Fate? Is Fate common?
blades in the dark and final fantasy star wars
since i've found pbta... it's like my forever home 😛
though I am willing to try fate/fate accelerated some time
blakeryan74 I know Final Fantasy liked to have characters named Biggs and Wedge in them but I would hardly call it Star Wars. 😉
EricfromNJ doh Fantasy flight Star wars 😛
Thinking about it, I can't remember ever playing Call of Cthulhu.
Greatwyrm you know...wait, Delta Green would count as Call of Cthulhu right? Otherwise I have only ever LARPed Call of Cthulhu
Greatwyrm Ditto, not played it or any of the various mythos games with the exception of The Cthulhu Hack.
Other ones on my list would probably be:
Anything by FFG
D&D Any after 2nd Ed
Pathfinder or any of its derivatives
FATE/FUDGE of any flavour, but I am prepping to run Tachyon Squadron
Fantasy Flight - anything
