I've played *a lot* of games Descended From the Queen - it's absolutely my go-to system to play these day. They don't all work well, but the ones that do I find myself coming back to again and again - For the Queen (of course), Final Lap, End of the Line, my own Descending the Stairs.
Currently playing in a PbF session at RPGGeek of The Wizard's Tower, where all of the players are apprentices in an ever-shifting tower after the wizard disappears . . .
Hoping to run a session of This Thing We Started in the next RPGGeek New Player initiative - it's the game that introduced me to DFtQ, about a group of scientists tracking down their creation, and I've never played it.
