This month, Invisible City Productions has brought something completely different to light: rules for a free swimming pool game called Roboctopus! The game is essentially a Marco Polo variant, but it’s a Marco Polo variant involving a bloodthirsty, sonar-equipped, mechanical mollusk, so I say “go for it!” It’s not as mentally stimulating as your average RPG session, but it lets you hit people with a long piece of styrofoam. What more do you need?
