EPYC is a game that plays best with a large number of players: We played with nine, though I think the more that you can have, the better. Looking through our own drawings from our game, I think that nine players gives enough time that most every drawing is guaranteed to go through some sort of funny mutation. Our game took 40 minutes to create and play all the way through, though overall playtime will vary with number of players.
Each player needs a pack of papers with sheets equal to the number of people playing. On the first page of the pack, each player writes a phrase or sentence of their choosing. It can be anything, but it should be something that can at least be somewhat represented visually.
You could choose "The bear ran for president and lost" or "cats playing rock band on the wii" or even something as straightforward as "the ball bounces down the stairs."
Then, you hand your sentence to the player on your left, and they draw your sentence on the next page of the book. They finish that drawing and then pass it left so that the next player can only see the drawing that they just drew. That next player captions it and passes it so only the caption is visible to the next player.
Since you're also seeing one page, you have no idea what the item was originally. You may have been trying to draw a singing cowboy, but the person seeing your drawing might think that you were trying to draw Yankee Doodle.
