I'm not sure Madden 13 is the best way to test the theory of playing easier games first. That can easily be a function of "jesus h christ this game comes out every year, I'm not going to play it every year." Compare to a game that doesn't have yearly iterations.
I took a look at trophy advisor, and the highest platinum it gives me was 31.07%. I can honestly say I wouldn't feel like going back to grab the vast majority of plats in that list though.
I am kinda inclined to go through and get some of the easier trophies the advisor lists overall... maybe get it down below 50% at the top or something.
