My son is 5 and since he was 4.5 he has said that he wants to be a level designer, making dungeons, puzzles, and mazes for games. When his preschool class asked the kids what they want to be when they grow up and he answered level designer, no one had any idea what he was talking about, lol. He then tried writing it, thinking they just weren't understanding his speech or that he was saying it wrong.
