The BIGS is an arcade-style baseball game that focuses on the gameplay rather than intricate details. It features power-ups and turbos during gameplay, making it more exciting. All 30 teams from MLB and their stadiums are included, along with their player rosters. The Wii version uses motion controls, including flicking the Wii remote and Nunchuk to speed up or use it as a bat when hitting.
The game has two unique modes: Rookie Challenge and Home Run Pinball. In Rookie Challenge, players create a ballplayer and try to lead them to the World Series. In Home Run Pinball, players aim to hit balls into windows and neon lights in Times Square, New York.
