Xbox Live Arcade is an online service operated by Microsoft that is used to distribute downloadable video games to Xbox and Xbox 360 owners. In addition to classic arcade games such as Ms. Pac-Man, the service offers some new original games like Assault Heroes. The Xbox Live Arcade also features games from other consoles, such as the PlayStation game Castlevania: Symphony of the Night and PC games such as Zuma. The service was first launched on November 3, 2004, using a DVD to load, and offered games for about US$5 to $15. Items are purchased using Microsoft Points, a proprietary currency used to reduce credit card transaction charges. On November 22, 2005, Xbox Live Arcade was re-launched with the release of the Xbox 360, in which it was now integrated with the Xbox 360's dashboard. The games are generally aimed toward more casual gamers; examples of the more popular titles are Geometry Wars, Street Fighter II' Hyper Fighting, and Uno. On March 24, 2010, Microsoft introduced the Game Room to Xbox Live. Game Room is a gaming service for Xbox 360 and Microsoft Windows that lets players compete in classic arcade and console games in a virtual arcade.
