PES is definatley a kids game, the music and little sound effect noises are annoying like a japanese cartoon and its far too easy to score everytime i have played the scores have been stupid, pes is more kid like becaude all kids want to do is score goals.
FIFA has alot more to offer, in terms of tactics etc you can really see them working on the pitch when you do ur own custom tactics and even more so when you turn the AI thing off and its you doing all the work.
I have always been a pro man because of the speed of th gameplay and the realism when you were playing a match but this year is poor, the ball seems to hold up when you pass the ball and its too easy to beat a man. The shots are more realistic and the goalkeepers are a million times better.
All the reviews i have read have said fifa is ahead of pro this year, so obviously alot more people feel the way i do than what dont.
