Xbox
The original Xbox was released on November 15, 2001, in North America, February 22, 2002, in Japan, and March 14, 2002, in Australia and Europe. It was Microsoft's first foray into the gaming console market. As part of the sixth-generation of gaming, the Xbox competed with Sony's PlayStation 2, Sega's Dreamcast (which stopped American sales before the Xbox went on sale), and Nintendo's GameCube. The Xbox was the first console offered by an American company after the Atari Jaguar stopped sales in 1996. The name Xbox was derived from a contraction of "DirectX Box", a reference to Microsoft's graphics API, DirectX.
Gears of War (video game)
"Gears of War" was first shown as an unnamed exclusive for the Xbox 360 in a behind-closed-doors presentation by Epic Games at the 2005 Game Developers Conference. The demo was presented as a technology showcase for Unreal Engine 3 that would run on the Xenon processor at the center of the new Xbox. It showcased a group of human soldiers patrolling a city at night that fell under ambush. The demo was noted for its overall realism, suspense, and visual clarity, helping to reinforce the argument advanced by Epic Games' founder Tim Sweeney for Microsoft to double the memory in the Xbox 360 from the planned 256 MB to 512 MB. This decision that would ultimately cost Microsoft tens of millions of dollars and restrict the number of Xbox 360 consoles available at launch, but allowed "Gears of War" and many other Xbox 360 games to run at 720p resolution.
