If you are undecided yet, the FIFA 13 demo will come out in a week, until then watch some gameplay here:

So, Would you go for FIFA this year once more?
Or PES, even though it has a crappy gameplay since 2011?
Or do you simply hate football?

Been playing FIFA for some time. It's quite fun, until the online-mode screw u around with bad connections and glitches..
