EA has had community events for as long as they've made games. The Game Changers is a completely different program. In the "old" days, community events meant inviting guys down a month before release and showing them the game, letting them have a tournament and sending them home to talk about how great the game is.
The Game Changers work year round with designers and the development team. During the months after release, we work to aggregate community problems (read: bugs, issues, etc.) and ensure that the team at EA are aware of problems so they can be addressed. We are also working to provide input and feedback that eventually become features in future editions. Starting 6-7 months before release we routinely go to EA for a week at a time to really dive into the upcoming release. We provide input on implementation, balance and outstanding issues.
I've personally been to EA three times since January to work on NCAA '13. While we are here, we concentrate on the game 12+ hours a day, provide direct feedback to the team. There are an interesting mix of people here. Some are guys who are what I would term "lobby" players, they are fantastic at finding "glitches" and other game play balance issues. We have people who are fanatical about dynasty, we have others who are extremely interested in the pageantry of college football and how it is represented in the game. To a fault, everyone wants the game we play year round to be football.
I would love if one day we got to show the "inside" of some of this activity. I'm a pretty vocal guy and while I try to be positive in general have many, many, many quarrels with the existing state of Madden/NCAA. We've been pretty brutal in round tables and dialog about things that need to be fixed, changed or upgraded.
Don't be naive enough to think that none of us investigate how sliders and ratings matter. After this time I have a very intimate understanding of what each rating actually does in game, because I've asked and tweaked, and broken things while at EA.
I'm not entirely sure why people continually insist on writing the Game Changers off. I've spend this whole week combing this forum (which I don't even post on most of the time), looking for bugs and well thought out study items so I can investigate with NCAA '13 in my hands. I've also tried to take the concerns here about new features and game balance and try them out in game so things that are potential problems can be identified NOW.
I'm as open about things as I can be (NDA and good sense does make me filter some things) and if you have questions or feedback I'm more than willing to listen and have a conversation, but posts like yours are a bit irritating to me, simply because you don't have enough understanding of what we do.
Some people go to the beach on vacation, I go to EA SPORTS and work on NCAA until my eyes hurt.=)
