What was the reason Madden and FIFA were able to port non-gameplay offline mode features to gen 4 and NHL wasn't? I understand M25 and FIFA were sort of "cross-gen" games, but what made NHL the exception in the inability to port functioning offline GM and BaP modes as a holdover before a more robust experience could be implemented in future iterations?
I can understand the technical problems of implementing EASHL into new tech, and getting up to 12 users playing at once, but why did the offline modes take such a hit as well? Additionally, such standard features in sports games like player editing.
