The Time Traveler And His Daughter

If you had a door leading to ancient times, what would you do? Would you engage in the trafficking of cultural relics, use advanced weaponry to bully the indigenous people, or simply establish your own empire?

If you had a door leading to another world, what would you do? Would you go to a magic academy to learn magic, embark on adventures with adventurers in ancient ruins, or simply marry an elf and bring her home as your wife?

If you had a door leading to a parallel dimensional space, what would you do? Would you take advantage of the differences between dimensions to become a pop star, a writer, a game developer, or simply the founder of an evil corporate empire?
