I doubt I'm the only one that downloaded and still plays the music playlist from NCAA 06.
And I loved the pennants that unlocked stadiums and cheats. I remember using about a half a dozen cheats in a game against Georgia. Totally crushed them by over 100. I also think that one game destroyed the team for a decade in my dynasty. (Kinda' regret doing that now.)
I also really liked the Spring Game feature that was in a few editions.
