Pepper's Adventures in Time

Pepper's Adventures in Time is an educational game/adventure game released in 1993 by Sierra On-Line. The project was based on a concept by Sierra VP of Development/Creative Director, Bill Davis, who also designed the game's main characters. The original plan was for this to be the first in a series of "edutainment" titles, in which the player, as Pepper, traveled back in time to set right mixed-up situations, surrounding famous individuals in history.
