How the game ends

So when does the game end? Using the 10 player game in our example, when it gets down to player 10 there will be one wrapped gift left in the center of the room or on the table. Player #10 has the same two choices that everyone else did (except for player #1). Player #10 can take the last unopened gift on the table, show it around, model it, read it or demo it etc. Or, player 10 can take another participants unwrapped gift (except retired gifts).
