like I said you guys do realize this includes single player campaign play correct?

This isn't just people playing online competitive multiplayer.

BTW

I have just the list but I also wanted to share an interesting data point: (that has been double checked) Halo: Reach was the number one game on Xbox LIVE for the past seven days and had nearly four times as many unique users playing the game on Xbox LIVE vs. Halo 3 for the week of Sept. 13.

This just a response to live activity from last week in which major nelson made an error.

  Halo Reach is not numero uno.

Online users is nothing for sales comparison... could be more users waiting the weekend for play Halo 3 than Halo: Reach.

And the comparison is a mistake from Major Nelson.

but they have to be online to be tallied, if more people are online now than when Halo 3 launched it makes the numbers incomparible. 

But almost 3/4 of the entire reason I love Halo is because of the single player.

What the eff. :(

How about scrolling down bottom of the  page next time

{Major} Now remember, REACH was only out for a portion of this reporting period. Let's see what happens next week

The difference is I'm not calling out the numbers Bungie is.

It just mean the 1/4 is simply bigger, 400% bigger.

"While we’re not privy to the methodologies and data used to compile the Xbox LIVE Activity reports published to Major Nelson’s blog this morning, we do know that last week’s numbers were well off the mark due to what’s now being called a “manual reporting error.” "

they're calling into question the XBL activity reports in Major Nelson's blog, not the sales numbers.  so in essence, no they aren't, so you must be.

The numbers are tallied from the 13th, reach came out on the 14th right. So, that one day made such a difference.
