I'm really tired of this discussion. It has been going on for months in various forums, and nothing really new has been said, at least that I have read, for a long, long time. There have been those on either side who have made themselves look bad by contradicting themselves insideout and backwards, and there have been those willing to concede both games are good and that it's a matter of personal taste (which is about all you really can say IMHO).
I do have one thing to say though, and I know I am contradicting myself by saying this argument is dead, then posting on here myself, but I do have to question why people put those who choose PES over Fifa down for being biased due to brand loyalty. If that were true, which in my case it is not - I gave both games a chance and made my choice based on and gameplay - then I guess what I'm saying is, "is that such a bad thing?" Really... is it horrible for a person to stick with and support a company who has done so much for the genre? Is it so much more noble to support a massive corporate entity like EA, who are driven only by market share, and steal all their ideas from Konami?
What Fifa still lacks is what it always will lack, unless they buy Seabass from Konami: originality. Where would Fifa be as a series if Konami never made PES? Nowhere. Where would PES be if there was no Fifa? Probably about exactly where it is right now. The Fifa fans should stop trying to convert PES fans, because if PES dies, Fifa will go with it, because they will never have anything new to copy. In my opinion, Konami fully deserve to be able to sue EA for all the game elements they have so blatantly stolen from PES, but of course, that probably wouldn't work given how much money EA would have to spend on lawyers.
