It's been done a million times. Look at the amount of suggestions on the PESfan suggestion boards, Konami don't listen. It even says on one of their sites, "any suggestions will be deleted because we do not accept suggestions for any of our games". I think they're frightened of getting sued for stealing someone's ideas.
I've written them letters for years, I wrote three in a year eight years ago, I wrote a couple more since then, and I signed about ten petitions. It's a waste of time. Seabass admits himself in one of the interviews that the team has been the same since the days of the SNES, and the game has always felt the same. He's hinted that this will change with PES2009 and so, God willing, next year will be the year.
But how many more times will we say that before we realise we're being conned? The FIFA fans realised the series was going nowhere in 2000 - or say 2001 for argument's sakes. That's three years of 3D football games before it clicked that it was the same shit each year. With PES, it's been going on for 8-10 years, and Seabass is still seen as a king, a true football fan, and all this bollocks. So it will continue forever, I think.
