On January 7, 2010, it was announced at CES that the upcoming Xbox Game Room would be made available on both the Xbox Live and Games for Windows Live services. However, games purchased with 240 Microsoft Points will only be playable on one of the platforms; either Xbox 360 or PC. A dual-platform license will cost 400 Microsoft Points. As the Game Room will be available to Gold and Silver Xbox members, the service will be free to use on Games for Windows Live. Arcade games will feature achievements and online leaderboards.
