Another idea for the game might be to make squad numbers more important. Remember when Beckham moved to Real and there was the big thing about the wingers shirt number as it belonged to Raul. PLayers should ask for their favourite numbers and get shirty (excuse the pun) if you don't give it to them.
Would it kill you guys to google the lower non-professional clubs and use the actual players names. I have a mate who plays for Parkgate and would have gotten a real kick out of seeing him in the game. Not many teams that appear in the game don't have a website of some sort, usually replete with pictures. Plus, I guarantee you that every player you list in the game will go out and buy it. It's got to be worth just that little bit of effort. The stats aren't important at that level.
