Microsoft announced today that first day sales of Halo 3 hit $170 million, beating the previous record of $125 million, for Halo 2, which was released in 2004. Not surprisingly, when I logged on to Xbox Live today, I had 14 friends online at the time, and every single one of them was playing Halo 2. That's a first, and even Gears of War never came close to that kind of coverage online.
