Together

From the introduction:

Together is a game of the imagination; it is played by talking to each other. In it you will take on the role of a character, your representative in the game who is an imaginary person living in the imaginary world that the game takes place in. The character has no representation in the game; they exist in the minds of those you play with only in as much detail as you can give them by describing their actions and the words they say. This isn’t improvised theatre so there is no need to act out their actions or put on an accent – but if you want to do that, so much the better.
