Madden has been the same game for like 10 fucking years now.
I really miss 2K football 
Madden 2010 is actually really good compared to the previous years, although it probably should have been at that level years ago.
2K football would be nice to have back though, the competition of Live vs NBA2K makes things pretty interesting. I'm a loyal 2K person with basketball, although after being away from so long, it might be tough for them to compete with Madden these days. 2K's online can also be iffy at times, although they've gotten better with it throughout the years it's still not as good as EA's offerings. Still, with EA's games you're stuck on their servers, sometimes the Japanese servers go down for maintenance and I can't play their games until they go back up.
One of my friends who I play Madden with tried to use his code in 2010 to unlock the online franchise mode but it wouldn't work. Never figured out why, although we didn't really care about the mode so it was no real loss. If there are bad codes out there, it's going to cause a lot of problems since tons of people only play Madden for the online game (myself included).
