I don't play computer games in order to lose to the computer. I play in order to relax, unwind, and score some goals.

I can pull results on World Class (never really fucked with Legendary), but it's difficult, I have to watch the computer dribble and pass way more than I care for while playing conservative, i.e. smart defense, and then I have to really strike iron to convert the chances I create. <--- Not fun. I just bump that difficulty down and get some Ws instead. When I need a real challenge, I play other people in online modes.
