when i stopped playing COD i think it was modern warfare 2 that everyone was playing. now i'm itching to start playing again but notice there seems to be 2 titles out right now. i would hate to buy mw3 only to find out that everyone is playing black ops 2. are both the current cod game? if not, which one do i buy? i'd prefer the mw style as oppose to the black ops, just going off of the previous black ops and mw games.
