Okay, for starters:
1. Whilst playing 2 vs. COM with a friend on Xbox Live, the majority of the time, the players automatically stop running for a through ball. It is beyond annoying, the sheer fact these "awesome" AI would stop running for a through ball and sometimes even turn around is ridiculous.
2. Edit Mode, if they can even call it that. Not being able to edit boots is bad enough, but deleting the Pixel Editor and Layer Editor is blatent suicide from Konami. Then to use the Vision Camera, and it's rumoured you can only have 8 or 9 slots in total for the pictures imported, meaning that you can't even edit all unlicensed teams properly. Possibly a mere 2 or 3 teams are able to be fully edited to resemble their realistic kits.
3. Greater variety of stadiums, okay, I admit they've put great detail into all 15 stadiums on the game. But I'm not going to be looking at Tier 4 in the Nou Camp when I'm playing am I ? They've decided to change Stamford Bridge's name to Tetro Blanco, paint all the seats red and then claim the stadium is located in South America.
4. The gameplay is far too fast, meaning it's got a much more arcadey-feel to it as opposed to a realistic football sim. I prefer methodical and tactical passing and build up, but it's pretty useless now when a pass will fly down the pitch etc.
