Microsoft is set to launch a new online PC game store called Games for Windows Marketplace in the middle of November.
Microsoft will have over 100 titles from various game developers and studios at launch, including many of the big hits from Microsoft Game Studios such as "Fable: The Lost Chapters," "Flight Simulator," "Gears of War," "Halo" and "Age of Empires Online." Other big titles in stock include "Grand Theft Auto III," and "Max Payne" from Rockstar Games and "Deus Ex: Game of the Year Edition" from Square Enix.
Games for Windows Marketplace will also host indie games too.
Like Steam, users will be able to access the store at anytime to buy games, or download them again if need be. Special deals will be launched to attract gamers to the service - such as weekly or seasonal deals.
"The Games for Windows Marketplace will offer PC gamers a robust lineup of games they love, easier navigation and purchase, and recurring specials such as Deal of the Week," Microsoft said.
