Well, based on EA Sports answers, somethings seem very clear to me:

1- EA Sports exclude a lot of cool features from FIFA because they have to release a game every year, so they can´t lost time.

2- There are a lot of limitations on FIFA just because they don´t make different versions of the game for different systems (PC, PS, etc).

3- They don´t worry about make easy interfaces to edit the game and put a lot of good leagues in the game, because it´s a user problem and we have to do it by ourselves.

what seems clear to me is that EA cant be arsed.

What I find puzzling is that EA claims that they do not have the time. If they don't have the time, they should hire more ppl, in my opinion, and is not as if they don't have the money. It's just that they are using more of their business sense than gaming sense, I believe, which is quite a shame.

Maybe EA dont have a lot of time, but if you look at the files for this years game and last years they are virtually the same, why did EA just not request the excellent patches, stadiums and so forth from the great patch makers on the web, if someone came along and asked me, would you like this or that to be included in the next fifa release i'd jump at the chance, thus leaving the designers to improve the gameplay

But they would never do such a thing, because that would mean that they admit that they are not very good.:(
