i think if u got a capable PC, then it is better to buy the PC version. i myself enjoyed the previous bf2142 on PC and the experience was top notch. then again, your call. if you are trophy or gs whore, get either the ps3 or xbox360 instead

about amount of players i wont be too sure. but back on the days of bf2142, i played a lot with people from AUS. good connection, healthy population plus they are good sports not sure how is the connection works now
