I often feel that a lot of these conversations don't have the nuances that I fit into (but I suspect that's been clear from the occasional times I've gone off on a tear off something I rebageled from you on tumblr, heh).

I don't particularly like D&D. I don't like class-level systems, flat out; the only one I find acceptable is Earthdawn and that's because a) there's actual worldbuilding about why it works that way and b) "levelling up" isn't the way you get better at thing, it's 'when you are good enough at thing you can choose to level up and unlock new things to get good at'. I have reams of comments about the failings of D&D as a system (some of which are neatly summed up by the current GM of my in-person group as "D&D is allergic to flavor").

What is my current in-person table playing? D&D, lightly hacked to stink less on the actual personality available on the character sheet front. And it's fucking great, because the campaign is built as the sort of thing D&D is made for ("people who are epic-hero exceptional and need to save the world via a variety of mechanisms that substantially include combat"), because we've built the flavor hacks, and, fundamentally, because we've got a solid roleplaying table.

The same table has also played other systems, mostly what I call "sloppy GURPS" ("we have character sheets in GURPS in case we need to roll checks on something but otherwise we're just playing"). I might see if we can put together an Earthdawn one-shot sometime if we want a break or want to play down extra people (or down the GM), or some other things. But at the same time it's hard enough to assemble our five adults for the game we're already doing.

My other current game plays Deliria and that is a hell of a lot of fun. It's the sort of system I prefer, but alas it was not popular enough to get a second edition to clean out the jank so we have to houserule a lot.

D&D was my ... third? Fourth? major system pickup. (Shadowrun, Earthdawn, the World of Darkness starting with Vampire, then D&D. WIth a sidebar into Paranoia on the way there but that wasn't a system to me such as a howling descent into madness. :D ) Doing my own game design meant I had to shake the idea that I needed super detailed combat rules for a game that shouldn't be combat-focused, but it wasn't D&D that got me into that mindset, it's every major system.

(I settled on "look if you have one challenge to handle a social conversation or pick a lock, you have one challenge to figure out how your fight goes, not a round-by-round bullshit", for the record.)

I keep meaning to have a look at PBTA stuff - there's a fellow who takes classes at the music school right after me, or did, and we had some gamer nerd sessions while I was hanging out - but I haven't dug into it yet. I'm fascinated by it as a sort of meta-engine that can be implemented in more specific ways.
