According to Major Nelson's list of most played Xbox Live games, Call of Duty 4: Modern Warfare has again (for the second time) taken the Live crown and bumped a very stubborn Halo 3 to the second slot. Juicy good! Not two weeks ago, CoD4 was crowned the most played Xbox Live game of the week, but then last week Halo 3 shifted from second to first. Now, this week, we see another hard fought switcheroo. Again, we welcome you to voice your ever important opinion on this Halo 3 versus CoD4 Xbox Live war in the comments section below. Be civil and be 100% fanboy.
