These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Traveller
Broken Base: With the release of several new editions over the years all of which drastically changed the key premise, it was inevitable.
Creator Worship: There is a reason the 4th edition was called "Marc Miller's Traveller".
Fanon: The setting practically invites players to fill in the blanks with fanon, referred to as "IMTU" for "In My Traveller Universe".
Follow the Leader: Most of Traveller's roots are in the Science Fiction literature of the '60s and '70s, but its initial success might have something to do with it coming out right after Star Wars was released.
