Genesys / FFG Star Wars -- I bought these on a hunch after reading the Genesys core rules, thinking if nothing else I'd have a nice, generic, more rules light, narrative focused core than Savage Worlds. So I expected to like it; I just didn't expect to really love it as much as I did.
Ironsworn --- I came to Ironsworn with lingering skepticism based on a "meh" experience with Dungeon World. But I really liked the vibe and tone of the rulebook, and the way it explained the core game loop.
The phrase "blown away" probably gets used too frequently, but it's the best way to describe my reaction.
This was a metaphorical shot in the dark. If Ironsworn had failed me, I would have abandoned PbtA style games forever.
But instead, I couldn't believe how compelling it was to play and GM. I couldn't believe how much better I now understood what PbtA was really trying to accomplish under the surface. I couldn't believe how evocative the baseline setting was, yet how portable the baseline rules were to other settings.
And more than anything I couldn't believe it was free. How in the world could a system that had given me some of the best roleplaying I'd ever experienced be given away for nothing?
