1.3 million people play Call of Duty 4
Rubin told Eurogamer.net last week that 1.2 to 1.3 million users play CoD4 on Xbox Live daily, and that doesnt include PlayStation 3 and PC gamers.
"Overall, even without the other consoles, we are beating the competition," he said. "PS3 numbers are monstrously huge. No other game has come close, either online current, or total unique users in a day.
"...Weve created a lot of heartache for a lot of companies who go up against it. I think Halos website says they get something around 845,000 to a million [per day]."
Microsoft Xboxs Live director of programming Larry "Major Nelson" Hryb confirms CoD4s Live dominance in his blog. CoD4 has been the most widely-played Live game for the past seven weeks in terms of unique users, topping Halo 3, which has been capturing the second slot.
The last time Halo 3 was on top was during the week of January 21.
