I'm having fun with my current CM game, even though it's highly edited.
I took a Conference team, Chester City, and put England U21 players on it. Then I put all the player "Potential Ability" to 200.
Obviously, I easily won the conference, and then Division 3. While in Division 3, I lost in the FA Cup final to Man Utd, but that still qualified me for the UEFA Cup.
I'll keep playing this game until I win the Champions League, or until I get CM4, whichever comes first.
Also, I don't think I've ever managed Juventus in the game. Kinda weird.
