As fellow old warhorses, are you guys this fossilized in your gaming foibles? Are there entire genres you won't play? Do you only ever run the same game system exclusively? This is all very weird, and wrong, and weirdy-wrong to me.
I have some systems I like. BX AD&D 2e 5e D&D. Gamma World, Star Frontiers. Beyond the Supernatural, After the Bomb, Albedo, Torg, Shadowrun, Marvel Superherous, and a few others.
And I have systems I do not like, Like gurps. 3e/PF and 4e D&D. and a few others.
And a few systems I'd like to try like TFT, T&T, CP2020 and quite a few others.
And a few I am on the fence about. Like 2e, Rifts, and quite a few others.
When you go looking for players always make it really clear what your intent is. What system/s are likely how when where and why.
Then expect at least 90% to not read some part and thus be incompatible.
I have been really fortunate in that the players locally have been open to playing about anything I run and same for my online players.
My original gaming group was pretty eclectic. We played Torg, Robotech. Beyond the Supernatural, TMNT/After the Bomb, MSH. Mainly as I was into Palladium stuff at the time and Torg because a friend brought it in and wanted me to GM it
