Honestly, it's not as realistic as everyone says it is...

User Rating: 5.5 | Pro Evolution Soccer 2010 PS3
I bought PES: 10 very recently just to see what all the hype my friends were talking about is. I already own Fifa 10, by the way.
So, I open the game up, and put it in my PS3 and a just do a quick game against Manchester United with Arsenal (North London when it's unlicensed). I started playing, and I was appalled how the players run. Konami maybe tried a bit too hard in this game.

I played through a manager mode, and got to the Champions League (I think this was where all the hype was!) and I was very impressed. The crowd in 3D! I thought I'd never ever see this in a Football game!
But, unfortunately that is the only real thrill I got out of the game.

An average 5.5/10 for me, but it could have been more if they actually had the money to put licenses for the teams.
Being honest here, but I think that Konami spent a boat load of money on the Champions league logos and the actual name, when they could have spent that boat load on licensing teams like Liverpool from Mereyside Red to their real team name.
