My first D&D was 3e. I knew a friend who played it at the local college gaming club. When I transferred to that college and heard an advertisement for the D&D College Tour 2000 on the radio, I went to check it out. I still have the tat I got (a cup, a badge holder advertisement for the D&D movie, and a bottle opener with the 3e logo).
We played 3e and switched to 3.5e when it came out. After that, some new people joined the club, and we started playing indie games like Dogs in the Vineyard. I recall playing in an aborted D&D campaign, but we most did other stuff for several years. I eventually ran a few one-off adventures in 3.5e around the time right before 4e landed.
4e was … okay. There were some things I didn’t like in the lead up to its release, but I didn’t quite feel as negatively towards it as my players did when we started playing. Most of our time spent doing 4e was with the player/GM I
wrote about in the worst player thread, so it wasn’t a great experience.
After 4e, I started running Pathfinder 1e and ran that for years. We tried the D&D Next playtest, which was variously okay. I did run
Murder in Baldur’s Gate using it, and thought it was pretty good. After 5e released, I ran
Lost Mines of Phandelver and
Hoard of the Dragon Queen. The former ended in a TPK (the PCs conveniently lined up in dragon breath formation for the dragon in Thundertree). We finished HotDQ, but I didn’t go on to run
Rise of Tiamat.
After that, we bounced around back and forth between systems. I ran another Pathfinder 1e campaign. This one was homebrew but set in Golarion. It ended up being the last PF1 game I ever ran. I also ran a homebrew hack of Fate set in Golarion, and we tried Dungeon World a few times. I finally shifted to a homebrew setting with Open Legend, which was just sort of okay.
I’m currently running a hex crawl, which has been run in several different systems. We started in 5e, switching after a TPK to Pathfinder 2e. I ran PF2 for about a year before burning out on it and proposing a switch to Old-School Essentials. My players were nice to agree, but I don’t think they really wanted to do OSE. We’re on Worlds Without Number now. I’m getting close to do with setting reation.
We have our second WWN session this Saturday, which will introduce the revised setting (v1 was Open Legend, v2 was 5e and PF2, and v3 is WWN). From what I can tell, WWN seems to resonate much better with my players than OSE did. I think that’s because it feels a lot like 3e in places, which is the game we played for so long.
In the spirit of the question, we’re not playing D&D, so I answered no D&D right now. Other players have run Delta Green in Savage Worlds, Mage: The Awakening 2e, Cyberpunk 2020, Call of Cthluhu, and Scum and Villainy; but they don’t seem to want to run a concurrent D&D game (or some other fantasy RPG).
