Template:Infobox RPG Teenagers from Outer Space is a rules-light comedy role-playing game written by Michael A. Pondsmith and published by R. Talsorian Games. It was inspired by gag anime such as Urusei Yatsura and Ranma ½. The game was first released in 1987, when anime was still mostly an underground sensation. The game is currently in its third edition, published in 1997.

At least two modules were published for the original edition of TFOS (as the series is often abbreviated). The first was "Field Trip" written by Dave Friedland and published by R. Talsorian Games. The second was "TFOS does Winterfest", written by Douglas Garrett, Paul Lidberg and Michael MacDonald and published under license by Crunchy Frog Enterprises.

In 2001, A2 Press published a TFOS universe expansion book named "The Landing" which was written by Michael Cox. More expansions were supposed to follow.


The basic setting of Teenagers from Outer Space revolves around aliens making contact with Earth and becoming infatuated with Earth's "teen culture". So much, in fact, that many aliens move to Earth, and enroll their children in Earth schools. As you may well expect, wacky hijinks ensue.


Players take on the role of either (somewhat) ordinary Earth teens (Humans) trying to cope with the "new neighbors", or Alien teens trying to fit in on Earth. There are eight stats, ranging from the relatively normal Bod (overall physical strength and agility) and Smarts (intelligence), to stats like Relationship With Parents (how well the character deals with their parents and other authority figures) and Driving. Skills, or "Knacks", are made up by players, with oddly descriptive names like "Drive Like a Maniac", "Fire Raygun", or "Avoid Being Harassed by Authority Figures" recommended.

Aliens can come in a wide variety of shapes and sizes, but are classified into three basic types:

This classification system can also be applied to non-human characters who are not necessarily aliens, such as robots and mythological creatures.

Alien Teens frequently have one or more bizarre powers such as flight, the ability to throw lightning bolts or breathe fire, shapeshifting, or psychic powers. Humans start with only one special ability, Fake Out (an uncanny knack for fast-talking greenhorn aliens into believing false information about Earth culture), but may start with advantages like increased running speed or durability, or outrageous wealth.


The rules encourage a lot of improvisational and character-based humor. The "GM's tips" section of the rulebook includes a list of suggested gag situations ("routines") the players will have to deal with on a regular basis, from jealous girlfriends, to drill-sergeant gym teachers, to nosey siblings, to unlikely interruptions for make-out sessions.

Influence Edit

Despite the apparent simplicity of the design, TFOS has turned out to be influential in the development of role-playing games. As the first non-mecha anime-based game to achieve a degree of commercial success, it was pivotal in opening the development of that genre. That and the simplicity of the system were major influences on the development of Big Eyes, Small Mouth. It has been very popular on computer networks and is still frequently used in Internet games.

Trivia Edit


  • Many of the "sample episodes" used as examples in the rulebook were inspired by episodes of the Urusei Yatsura television series.
  • Despite the game's obvious anime roots, the art style used in original versions was inspired more by that of Western comics. The current version has a more anime-inspired look, partially modeled after the style of Urusei Yatsura creator Rumiko Takahashi.
  • TFOS Does Winterfest was followed up with a book called The TFOS Yearbook, which was based on a long-running online campaign run over the CompuServe network.
  • The Ianus Games RPG Star Riders uses the TFOS system under license.
  • For several years plans were made to do a TFOS-based RPG based on the Ben Dunn comic Ninja High School. The end result turned out to be an article published in one of Antarctic Press's anthologies.
