Following the top-rated simulation-style NBA game on PlayStation and Xbox consoles in previous years, the 2K Sports series expands to play its pro basketball on Wii and PSP with NBA 2K10. Across all platforms, the game retains the basic flow and feel of the 2K series' play style on the court, while refining league management features and adding new presentational elements intended to bring NBA authenticity. The series' Signature Play system builds on the player-specific styles featured in earlier games. New Signature Tendencies influence player decisions in the heat of the moment, and new facial expressions convey emotion while adding realism to the presentation. The 2K Sports "Association" franchise mode returns, offering almost complete control over trades across the league, and the ability to run real-time practices and assess how players work together as a team.
