: ---------------------------------------------

: Some things to point out: Battlefield 4 just launched and can't even beat
: MW3.
: Halo 3 became free mid-October, and managed to beat out Halo 4.
: Black Ops I, a game released in 2001, can still beat both Halo 3 and Halo 4.

: My point of view? I expected Halo 3 to beat out Halo 4, since it was free,
: assisted by Halo 4's population.

: Thoughts?

FYI

Blacks Ops I 2001? Mistake?

Halo 4 population did not take a hit when Halo 3 became free. It remained static to increasing. Source, Halocharts.
