We did a one-shot to test it out tonight, using the Codex VTT,
How'd you find that?
I think the biggest non-technical issue I had is that it felt very "gamey." I'm so accustomed to running games with 5e/A5E in a continuous way, that jumping from vignette to vignette is jarring.
That's fascinating, I was expecting you to go with the design or combat here and not scene framing! To me, the "continuous way" is far more gamey then scene framing techniques that narrative games have been emphasizing for a while; continuous style play is a very D&D-ism thing (probably arising from dungeon play?), whereas distinct scenes with a frame/conflict/resolution are what you see in media like novels and movies.
So, how are your games going? How many sessions have you had?
Just 3 so far, but after two of the Tomb we're giving a whole from-scratch campaign a shot. People have been really enthusiastic about character building (definitely hits some of the PF2e style notes there and I hear from the players that the Forge Steel tool is really good), the Complications are a heck of a lot of fun.
How easily are folks picking it up?
It's got a fair bit of keywords but thankfully the book and quick references have let us work through most things quickly as we go. Some of the phrasing is clumsier than 4e which can trip up a bit. Generally pretty easy though, the math is so flat and simple with that 2d10+(limited modifiers).
