I do not know how many of your friends on your friends list were playing halo last night, but I saw more people playing infinite all at the same time than I have ever seen any game since halo 2 came out.
I am very curious to find out how many people were simultaneously playing halo last night and I’m sure Microsoft will tell us.
All I know is if I had that many people on my friends list playing there had to of been millions and millions of people playing last night.
