So basically, the game leans more heavily on improv than most. In addition to everyone building the world together, players can spend metacurrency (Fabula Points) to do things like, say "there's someone I know who lives in this town and might help us," or "wouldn't it be cool if this mysterious figure we were just introduced to was secretly Frank's character's long-lost wife?" If it affects another player's character, like that second example, the player has to agree. If nothing that's already been established contradicts the idea, it gets added to the plot.

My players don't really use this facet very often, but it has the potential to be really neat, if also to make the DM throw out some notes at times.

I'm hard pressed to say what my personal favorite system is, but currently I'm saying Fabula Ultima.

Then the DM starts playing this music.

My mom's favorite is the phrase "nothing discernable happens."

"So ya know what happens when you..." is a terrifying way to begin a description of such a thing, too!

But you don't understand! The Wraeththu are just better than us, so they know how to make things that look weak from the point of view of a dumb, inferior human, but they're actually even better than katanas, which we all know to be the pinnacle of human weaponsmithing!

Oh, wow! TBZ reference!

Yeah, CthulhuTech has issues...

Cities Without Number's paid version has what is very clearly "Shadowrun without the Shadowrun rules." I haven't tried much of the system, and none with the magic stuff, but it might be pretty good?

I wish so hard that it had been my idea, but someone on a forum I'm on thought of it first.

Congrats! I hope it was a good time!
