Okay, so there are a few issues facing Madden NFL 15 .
Beyond lower-than-anticipated review scores, it seems the game suffers from a variety of bugs and glitches. The good news is that Electronic Arts is well aware of these problems.
They've set up a dedicated status page for the game that lists the game's critical issues. It also tells gamers what the developers are doing to fix those issues, so that's good. Problems include: Inability to redeem Madden Ultimate Team codes, wins and losses not being recorded for online Connected Franchise Mode head-to-head matches, and various server problems.
If all you want to do is pop in the game and play, however, without being connected in any way, you should be fine. Remember the days when that's all you wanted to do? Pop and play? Yeah, me too.
