Amazing stats for an amazing game. Best online multi-player on any console (IMO).

I love the series.  

How can there be 15 million unique users if the game sold 10 million? pirate copies?

^^And friends liking it so much that they buy live and come to your place to play.  I had a whole bunch of friends who did that.

Yeah for any game that would be incredible, Halo 3 deserves it. Just because its Halo doesn't mean a thing.

this is a noob question, how can 15 million people enjoy it, when it only sold 10 million?

first game I ever played on my very own 360.

so you're saying that 5 million of second had copies are sold? link to support that?

In less than 2 years it had 1 Billion games played....I'm impressed. For any game thats a hard feat to follow. The thing that's really amazing is that over 600,000 individual players play per day.

1. Used copies
2. Pirated copies
3. Rentals

Happy Birthday to an amazing game.

After Reach is done. I hope they give Halo a long rest. Unless the story can stay as amzing as it still is.

Use your talents Bungie to give us Bungie lovers more awesome gameplay in a new setting and new story. Well done. My 2nd faveourite game this gen.
