It's converted me from PES to FIFA.

I've not bothered with FIFA for a good 7 to 8 years because I've always stuck with PES. However, after playing the demo I was amazed just how much it had improved. FIFA now has the authenticity and great gameplay, which in my eyes now overhauls PES. The online 10v10 did the final swaying and I must say it is an absolute hoot and the BAP single player is an addition I have been longing for too, whether it's taking over an existing player or creating yourself. Even just practising shooting with one player is loads of fun and you can spend plenty of time faffing around in that mode too without getting bored.

When it comes to dificulty, on the harder levels the game is quite tricky and you really have to have your wits about you, as the AI is very very good.

If you're used to FIFA then there's no doubt that you'll stick to it, but if you're a PES man, you may have your head turned by this.
