Mekton is a role-playing game which centers on the conventions of mecha anime and science fiction (although it can easily enough be adapted to other genres like police drama or high fantasy). It has seen several editions since its introduction in 1984, the most recent, Mekton Zeta (メクトン Z; a reference to the seminal mecha anime series Mobile Suit Zeta Gundam) being first published in 1994
