Word from Grifter is "The Schemaverse Championship" approved to return to DEF CON 25.
Description: "The Schemaverse is a space-based strategy game implemented entirely within a PostgreSQL database where you compete against other players using raw SQL commands. Use your SQL skills to interactively command your fleets to glory during this weekend-long tournament for the database geeks. Or, if your PL/pgSQL-foo is strong, wield it to write AI and have your fleet command itself while you enjoy the con!"
