How much money did Halo make on its first day? $100 million, according to Microsoft and EB Games, says GameSpot. Not bad.

Editor's Note: Comparisons keep being made to the opening day takes of Hollywood films, and there's no sign that such comparisons will stop anytime soon. However, they're probably not very meaningful. Movie tickets are cheaper, the potential audience for films is larger because there are no hardware requirements, the chance for multiple viewings is much greater than for multiple copy purchases, and films rarely offer pre-purchasing for tickets months in advance, meaning that the purchases for Halo 2 are stilted towards the first day in a way that looks similar, but is motivated by different circumstances, than for films. But still... not bad at all.
