You may think there's better things you can do with 15 minutes. Tidy your room, for example. Marinate tomorrow night's steak dinner. Take a slightly-too-long dump while you finish a chapter in that book you're reading. All good things, but come on, if you can spare the time for those, you can spare the time for a 15-minute walkthrough of Red Alert 3 gameplay. Construction, combat, the works.
