Hall of Infinite Doors

You are now in a medium sized room with a door in the center of every wall. In the center of the room four teenagers dressed as different fantasy characters sit around a table with a game board, figurines, dice, sheets of paper, pencils and handbooks. It looks as if they are all playing some sort of Role Playing game. One teenager is dressed as an elf, one as a dwarf, another as a monster, and the final one is dressed up like an old man wizard. What will you do?
