I love NBA2k's Association, play it a ton. But I also love my ManU CM in Fifa12. Why? Because I am a Cavs fan and a ManU fan. I see your point, as well as a lot of the other guys, but I offer this. I am 45 years old. Started cheering for the Bengals in '88 with Boomer at the helm. Now we're finally back to Andy Dalton as the first legit QB we've had. If I was playing one Franchise mode that included them all I would've seen a bunch of crappy QB's come and go, as well as many other Bengal greats and not so greats. A lot of guys have been saying they want realism, but how could you duplicate the Boomer to Dalton reality? You can't use NCAA, it's only 4 years worth of guys at best. Custom rosters? Still tied to NCAA in real life.
At some point there will be a fantasy aspect to try and keep playing for 30 seasons. And it wouldn't last as long as people think, based on the pace you would have to play 30 season before next Madden. Even if I play at a pace to make this last a full 12 months, Andy Dalton retires in 6 months, if I'm lucky. I've also got a full 8-9 years of fake players filling the league.
I guess my overall point is this. I am a fan of the organization/team first. The players are secondary. They will come and go if I stick with my Career/Franchise/Association long enough. I understand the point about not being able to play other games. I really get the not being able to play with other friends on the same console. I guess where I have found myself befuddled at the level of anger is the whole ratings/equipment editing/accurate rosters thing. Any videogame "career" mode is going to turn towards the fantasy element pretty darn quick, that is if the gameplay holds a person long enough....
