Microsoft's Marc Whitten announced in a blog post today that the company would discontinue Xbox LIVE for original Xbox consoles and games, including both titles for the first-generation Xbox and Xbox Originals. The switch to Xbox 360-only service will take place on April 15, so you still have a couple months to squeeze in some Halo 2 multiplayer action.
In justifying the move, Whitten explained that the decision wasn't "made lightly," but is necessary to facilitate the evolution of Xbox LIVE. "To reach our aspiration, we need to make changes to the service that are incompatible with our original Xbox v1 games." Affected members will receive messages via LIVE and email over the next few weeks for "more details and opportunities."
In his closing, Whitten said he believes forthcoming changes to Xbox LIVE and Microsoft's Project Natal will make 2010 a landmark year in gaming and home entertainment.
