-In PES-4, the 6-star level was too easy...
-Scoring was too easy...
-Through lobs were also easy...
-Goalkeepers were worse.
-In WE8, the 6-star level is tougher.
-Scoring is closer to real life. 0-0, 1-0, 2-0 happen A LOT more often. Of course 3-0 and 4-3 still happen, but believe me at a really less rate. It's far more realistic, believe me. Winning 3-0 and 4-0 on a 6-star level in PES-4 wasn't so much fun on the long run... In WE-8 (on the 6-star) you have to earn your goals.
-The percentage of scoring from magical thru lobs has definetly decreased.
-Goalkeepers are better... sometimes stupid... but noticably better.
so WE-8 may be a good choice, so where's the catch? There it is: NO PATCHES... After Wolf's patch you'll have a really HARD time googling around for patches... everyone seems to be interested in making patches for only PES4... that's the big drawback...
But after Wolf's patch, I doubt you'll be in desperate need for any other patches...
Plus, I'd choose improved gameplay over countless patches... coz there simply isn't any gameplay patch that makes PES-4 like WE-8....
All these differences as I said are very hardcore... you get to notice them after about a month of playing... NO significant graphix difference...
If you are to choose from both, I'd say get WE-8... And hope someone pays some attention it... (Wolf said once that in the future all his patches will be for WE-8, so who knows?)
