One of the biggest complaints from Madden fans since the game was released is the poor implementation of preventing quitting. In years prior players who quit received a loss and players who were quit on could either count the game or continue versus the CPU. However, EA’s online architecture was revamped to a one-to-one connection between players. While this offloaded bandwidth on EA servers, it caused a huge problem for the Madden online community: quitting with no repercussions.
However, EA has listened to the community and implemented a fix. Whether or not it meets your expectations though is questionable.
