The two most important aspects of FB-Pro for me was the Play designer and the head-to-head online ability in coaching mode. Those two things set that game apart from anything before it or since it died with the 99 version fiasco. I own a plethora of Sports Sims and I almost never play single player...usually my experience with single player is to learn the chronological order of events so I can play in/run an online league. FB-Pro98 was hands down the greatest Football Simulation ever made!
These two things I am hoping make it into BTS, I realize having it in the first version is probably a pipe dream, but it's never too early to "dream" about the next great Football Simulation
