Dave's OOTB All Madden (winning bores me) sliders
 

If I win 4 in a row I start to get bored. I'm playing with the Bears and have yet to have a winning season (4th season, playing every game) which is fun for me. CPU is slightly overpowering which forces me to play better and draft better which makes winning that much more rewarding. For those looking for an organic challenge these might provide a solution, I'm addicted to Madden again.
