Third "New to GURPS" post still on-track for Monday, but in the meantime,
this is the GURPS game I'm running at Gateway 2015:
The Warriors: Come Out to Pla-ay
When all hell breaks loose at the giant gang meeting in the Bronx, four members of “The Warriors” – – Ajax, Cochise, Snow, and Swan – – find themselves alone and falsely accused of murdering the leader of the most powerful gang in the city. Can you bop all the way back to Coney Island with the cops, every gang in the city, and the real murderers hunting you? (No prior knowledge of GURPS or the movie required)
