Super compact and focused, with mechanics feeding into one another well. Excellent for an abrupt and quick sessions.

Distills characters down to a core aspect with some perks (trump cards) and quirks (weaknesses), and the mechanics behind challenges are extremely simple. It might feel a little limiting but that intense focus lets you tell at a glance how easy or hard a character will find doing something. The perk and quirks use a system where perks cost karma to make challenges easier and quirks make challenges harder in order to restore karma. This encourages players to bring their characters weaknesses in order to keep using their strengths in play. The optional rules cover a lot of bases and add to the existing rules rather than replacing them.

All in all, good stuff.
