I have never bought a WE/PES game before. I've always played FIFA, but I bought WE8 today, and played one game: Barca v Real.
My first impressions are fairly positive. I do like the game play, for the most part. However, I'm so used to the FIFA controls that I don't like how the WE controls are setup, and I haven't messed around with them enough to get them how I want them to be. I also don't know all of the controls yet.
There are some things in WE that I don't like. I really don't think that the flight of the ball from goal kicks and long lobs are very realistic. It seems that the ball is weightless and floats through the air for entirely too long. It's almost as if you're playing on the moon with zero gravity. Also, the menu graphics, and the graphics in the game, such as the player names, the score, etc...are really ugly, and are an eyesore. The music is horrible, obviously, but you can turn that off. Also, is there a way to turn off the radar? I don't want to see it.
However, I do like that you can take a short corner, and I like that you can choose between a direct and indirect free kick, that's great. I also think that alot of the player movements are quite nice. FIFA has improved its' player movements, but my first impression is that WE has done a great job with player movements.
Of course FIFA players love that they get almost every license, and that makes the game alot more enjoyable. However, I think that the things the FIFA lacks are made up for in WE. I'm sure that the more copies Konami sells, the more licenses they'll be able to buy. Everyone would love to see WE get full license for the EPL, that would really be great, but for now, we'll deal with fictional EPL teams, and just enjoy La Liga and Serie A. I couldn't care less about the Dutch league, to be honest. There are only 3 teams that are quality anyway.
If Konami would stop calling their game 2 different things, and call it either Pro Evolution Soccer or Winning Eleven, and release the game at the same time around the world, alot more people would buy it. They need to discover the power of marketing, because what they do now is quite stupid, and makes no sense.
I'll post more of my likes and hopefully not many dislikes as I play more games. Until then, enjoy the game.
