Demo of this felt great, but will hold out for X1 launch, as I'm getting it bundled.
As an ISS and then PES player going back to the SNES days who jumped ship to FIFA with 10, I was all ready to come home to PES again this year. I though FIFA 13 and PES 2013 were pretty much equal last year and as EA have been getting on my nerves recently I thought I might switch back. But sadly a combination of no next-gen version and trying the 2014 demo the other day has changed my mind. I was disappointed to find that with the new engine a bit of the old magic had gone, the graphics and animation are both great but it just didn't feel like PES to me.
Sticking with FIFA, and having tried the demo I'm more than satisfied that this is the right decisions.
