In this paper, I present simulation as an alternative solution to the problem of commonsense knowledge acquisition. This position stems from the fact that commonsense is essentially redundant shared experience over time and posits that reality computer games could be a forum in which computers could gain this shared experience from a human user. The implementation and initial results of a learning program, ThoughtStreams, is shown to have some initial success in predicting commonsensical future events based on past experiences in a simple simulation game environment.
