I disagree that the game has improved more from 25-15 than 06-12. '06 might be the worst madden ever. From that through '10 is the bigges improvement IMO.
It's been the same segmented approach with this new team. The physics engine looks about the same, maybe less impactful since its implementation. True Step looks untouched since its implementation. Outside of graphics & presentation, I'm seeing very little of the improvements listed for '15.
I think Big nailed it here. With the core coding firmly in place, I wouldn't guess there was as much turnover at EA/Madden as there has been. Knowing what I know, the change from Ortiz & them to Ian & Co was more noticable to me. My guess is that we won't see much change until the real coders are replaced.
Hopefully this has been "turned off" in released vids, because I'm not seeing any of this. I know, I know, next year is THE year.
