The card makes references to role-playing games' propensity for result tables, basing each table on a Doctor Who cliché/convention. Critical Success: New Who has up to now garnered more critical success than Classic Who (winning Hugos and the like). A critical success in a role-playing game usually involves rolling a top number for the best possible result.
