Video games that are published by Nintendo are exclusive to their own game systems. They don't license their games to rival systems like the Sony PlayStation 3. Some games that appear on Nintendo systems are "multiplatform," however, and can also be obtained through the PlayStation network.
Some third-party publishers independent of Nintendo will publish games on Nintendo's systems as well as on the systems of other companies. Some examples of games that were published on both the Nintendo Wii and the PlayStation 3 are "Star Wars: The Force Unleashed," "Madden NFL '08," "Tiger Woods PGA Tour 10" and "Goldeneye 007: Reloaded."
