Discs of Tron will be America's XBLA game for February 13, according to this.
The Disney game's all about chucking discs at each other until one of you falls of a platform. It's probably more fun than it sounds.
"Discs of Tron is considered an arcade classic as it mesmerized fans who wanted an entertaining and challenging experience derived from the innovative film,” said Craig Relyea, senior vice president of global marketing, Disney Interactive Studios. “The game’s release on Xbox LIVE Arcade enables multiple generations to play the addictive game in both its original form from 25 years ago and an enhanced mode with upgraded graphics and sound."
