Glitch

Glitch is the first modern installment in a long-running series of games (starting with the RPG "Nobilis") for people who like recreational philosophy and metaphysics and thinking about how their fundamental experience of the world works. These are games built, from the ground up, to take thought experiments and goofy arguments and self-expression on the core of one's meaning and identity and blend them in seamlessly with the banter, conflict, exploration, and (in this case) mystery solving that you'll find in a tabletop RPG.

Sound interesting?

So, this particular game is a game about living in a broken world. It's a game about hope and struggle.

It's a game about people who've found mistakes in the way the world's put together; seen that the world itself is wrong; and, therefore, of course, developed eldritch powers, gotten inducted into a mystical society, acquired a passel of enemies, frenemies, and dubious allies, and picked up a tragic backstory.

Oh, and, just possibly, a horse.

And/or ... a crown?

Anyway, though, the most important thing they got, the most key and the most critical, was the power to fight back, the power to make answer to this vale of suffering, this vast great hill of woe: a literal or metaphorical world-slaying weapon, just tossed into their hand, only, you know, the problem is, and they all do eventually figure this out---at least the player characters do---

World-slaying weaponry doesn't actually help.

Fixing things with a world-ending weapon, well ... that'd be like blowing your nose with a trout!
