Ok, i played FIFA 07 (PS2) for the first time today, so i'm finally qualified to comment. So here goes:
THE GOOD:
-Gameplay is less scripted than before. Its a little more random with stray passes and deflections, so its clear EA have been looking closely at PES.
-Presentation is fantastic as always. Nice menu screens, overall very polished.
-Great audio and atmospheric stadium noise (although a little quiet).
Also you hear national anthems before playing International games. I love this touch!
-The licenses. The amount of leagues is brilliant.
THE BAD::no:
-Still too scritped to tear me away from PES.
-Shooting still seems a bit random at times.
-No Holland national team from what i could see. Maybe more missing but i didn't have time to look properly.
-Graphically inferior to PES. Colours are too bright and kindergarten-ish. Distance blur effect is seriously overdone so that the graphics lose any sharpness and clarity. Players seem a bit jerky when running.
-The player models are a bit shabby and all players look the same build and height. They still have a ape-like stride to them, too.
-Limited tactical options.
OVERALL - Buy PES6, but FIFA 07 maybe worth a look.
