Ars writes: "At its core, the downloadable Costume Quest is a game about imagination. It's about what it's like to be a kid, put on a blue cardboard outfit, and imagine that you're a huge, awesome robot. Or a unicorn. Or a ninja. Or even some sort of strange french fry monster. The game manages to capture this feeling perfectly, both through its charming presentation and its hilarious dialogue. Unfortunately, the actual gameplay doesn't quite match up to the same standard."
