B/X in 1981 in 6th grade transitioning shortly thereafter to AD&D. In early to mid 80s also played much Gamma World 1e and a bit of Villains and Vigilantes and Star Frontiers (got my sister to play that last one a few times). In to Star Fleet Battles in HS for a while for my one fling with a miniatures game. Made characters for things like Champions, later Gamma World, Traveller, DC, Marvel Super Heroes, Twilight 2000, and Phoenix Command sometime by early college but didn't play more than a session or three at most. Switched to 2e in gradschool and loved it and then got lots of VtM 2e in and lots of MtG and some Decipher SW:CCG. Out in the world, loved 3.5, with some PF, SW, VtM, and one or two others, but group drifted apart for moving and jobs. Dipped toes in 4e along the way and meh. Next decade out in the real world played a variety of things for a few to several months at a time: 1e, 13th age (one DMs favorite), Fate, Shadow run, a Cthulhu thing or two, and a few others. Sidetracked playing MtG. Now running 5e and playing in it (with a bit less MtG).
When looking for people to play with it seems like picking the big one (or from the big two if there are a big 2 like when VtM 2e was huge) makes life a lot easier. Once you have a steady group it seems not hard to get folks to try a new game... if the group hasn't had to by too many other new rulebooks lately (knowing it might be the only time they use them if the group isn't crazy about it).
Do PF and 13th Age count as D&D?
I wonder if the two big differences between board games and RPGs are how long the steady time commitment is and that for the former, only one person needs to own a copy for everything to be smooth. Hard to have everyone show up with characters for an RPG if they have to pass around the rules.
Also have played tons of bridge (twice weekly if schedule allows), chess (team in HS), rummy, cribbage, euchre, canasta, and multi-player solitaire for classics, and a lot of Ascension for board games. Have a friend who has 6+ book cases full of board games, so I've played a few dozen, and own a handful, but don't play any regularly or go to regular game nights. Own a copy of Titan (played several times in grad school), but haven't roped anyone back in to playing. "This game is Bonkers!" is criminally underrated among kids games.
My 11yo son enjoys 5e and MtG and a variety of classic card games, and has tried several board games.
