I don't think it was far ahead for it's time as there were other sports games out at that time that recreated those respective sports just as well.
What Codemasters did do well and so many others have failed to do, Big Ant included, is get the basics right. DBC is in my opinion better than what has come out since overall and have been revolutionary in some areas, but there are still things that other games did better and I do wonder whether if DBC didn't have the career mode would we be rating it above EA2005 for example? There's no doubt Big Ant are on the right track but there are some glaring issues which to my knowledge would be quite easily solved but as yet have failed to be addressed.
