This seems unfair, at the time of this chart Halo4 is 2 weeks old and bops2 only 1. So it is still the "new" game people want to check out. A real test would be to actually wait tell after Christmas and at the end of Jan. Because alot more people will get the games this month and by the end of Jan you would have 2.5 months of real data on which game is played more online. Just a thought.

RedSoloCup i knew that call of duty would dominate halo, it always has always will haha

Call of Duty is also bigger because it's on all consoles but halo is only on xbox and is still keepeing up with it.

Yea because they brain wash kids to forcing their parents to buying it.

call of duty as grown so much since halo 3... so im not sure the comparison is really fair.
Although halo is getting more popular, black ops 2 is terrible and halo 4 is good all around

Ahaha i thought Halo 4 would win for sure.

CoD4 was the best one

halo 4

i honestly get bored of any call of duty within 2 games, except cod4.

Spaceman_Stu Of course Black Ops 2 sold more. Black Ops 2 was a genuine, revolutionary, ground-breaking blockbuster just like Modern Warfare 3! Black Ops 2 actually takes skill, as with all Call of Duty games, unlike those pesky "run and gun" games like Halo, Battlefield and Counter Strike. Those take no skill whatsoever! BO2's gonna get GOTY, not some "poorly designed" game like AC3, Borderlands 2 or Resident Evil 6. Those games NEVER get GOTY awards unlike the genius masterminds behind Call of Duty, the most delivering tactical FPS in the planet. The US Army should get rid of the Americas Army simulator game and start using Call of Duty as the new military simulator because of it's extreme realism!

Obvious sarcasm is obvious. Halo and Battlefield are easy as hell to play if you're good at Call of Duty. Counter Strike however is actually challenging, but Halo and BF shouldn't be mentioned with it.

It's not IW/Treyarch fault the game blew up as big as it is.(well it kind of is but yea.) Call of Duty was never known for it's "extreme realism" it has been an arcade shooter since the first one.

Oh and it's = it is. I don't think "because of it is extreme realism" makes sense. The word you're looking for is "its." May not seem like a big difference, but in college mistakes like that will annoy the shit out of your professor.
