I have both Psp Fifa 08 and Psp PES 2008 and both are good in different ways.
Fifa has the licenses for more leagues and national teams and PES the better grafik and player/ball movement is better.
I have an update for PES and the game is more authentic and nearly to the standard of Fifa
That they gain in difficulty as you go up a standard is normal and then requires a lot of training as is in real life.
But people they are games and one can`t expect to do eveything straight away because otherwise its not fun.
Fifa or PES i can`t say which is better,try them both out or look at a mates and decide for yourselves.
This game is very good for football fans both young and old,younger players should get a little help at first.
I have also aquired a second battery because when you start playing they are both very addictive and before you know it the battery is empty.
gets 4.5 Stars (good for authentic play:players, teams,leagues)
gets 4.6 Stars (realistic movement both players and ball and with update liverpool are no longer merseyside red)
I hope this helps
