"Character Quest is an interactive fiction game created to review proper English for 5th graders. Following the format of common test questions for this age group, passages are presented with grammar, spelling and punctuation puzzles. Players take on the role of the main character and are stuck inside a mysterious house trying to free all of the storybook characters trapped within the house. Each room has one character to interact with. The characters are straight from popular young adult novels. (See the Reference section to identify which books are used.) Given three options (sometimes 3 characters, sometimes 3 objects) students must identify which character or object is the genuine article and collect it. To identify the correct person, object the students must identify which one is grammatically correct, as errors represent imposters. Some characters will need items returned to them also, in order for them to return to their story."
