Everyone you encounter knows English. If the world has any languages of its own, you will only encounter 1,
and only in bits and pieces
All pop culture references refer to modern-day U.S., to the exclusion of any other time, place, country, or planet
There are no strange diseases you haven't been vaccinated against, all food is non-poisonous unless specifically made otherwise by the antagonist, the atmosphere contains human-friendly gases only, and all physical laws such as gravity are identical to Earth
If your dream was to explore a new world, as soon as you actually end up in one your #1 goal immediately becomes returning home
