  The process of playtesting a game is subjective, expensive and incomplete. In
this paper, we present a playtesting approach that explores the game space with
automated agents and collects data to answer questions posed by the designers.
Rather than have agents interacting with an actual game client, this approach
recreates the bare bone mechanics of the game as a separate system. Our agent
is able to play in minutes what would take testers days of organic gameplay.
The analysis of thousands of game simulations exposed imbalances in game
actions, identified inconsequential rewards and evaluated the effectiveness of
optional strategic choices. Our test case game, The Sims Mobile, was recently
released and the findings shown here influenced design changes that resulted in
improved player experience.
