Doing some simple math, GameDaily estimates that 52% of Xbox 360 owners in the US purchased a copy of Halo 3. With 4.1 million Halo 3 copies sold in the US through November and 7.9 million Xbox 360s purchased to date, it appears like a simple enough conclusion.
NPD's analyst Anita Frazier says the power of Halo 3 is evident in the fact that it clearly drove Xbox 360 hardware sales in September, even more effectively than a price cut would. Halo 3 may not make every outlet's game of the year round-ups, but it's sure to receive game of the year from Microsoft's accountants.
