Gears of War 3 is the big game on Xbox 360 at the moment having launched worldwide today (20th September) and being enjoyed by thousands of gamers.
The current active users and earlier this evening there were around 300,000 online gamers playing the Arcade co-op campaign, and the various versus modes. The figure has dropped a little since then, but these are huge numbers especially as they do not include gamers playing the campaign offline. We already reported on 170,000 users this morning, so there has been a steady stream of gamers throughout the course of the day. We can only speculate as to how many units were sold today.
