When Games for Windows Live's Games on Demand service launched in December we said it was "marching onto the [PC digital distribution] field about an hour after the match ended." Three hours later (in metaphoric time), the service announced today it will offer day-and-date game releases from publishers 2K Games, Capcom, Microsoft Game Studios (what a coup!), Rockstar Games, THQ and Ubisoft. We can't help but imagine Steam, Impulse and all the other digital distribution players at their post-game parties laughing.

The initial day-and-date offering by the service is Ubisoft's Prince of Persia: The Forgotten Sands. At the same time, the Prince of Persia games The Sands of Time and Warrior Within are each $2.50 -- which seem like much better deals than the aforementioned title. The service has also added several more games, which we've listed after the break.
