For me, the celebrations are minor, but a start (though I agree more non-TD celebrations are 100% needed).
-I want to see the home crowd going nuts (when appropriate, of course
). The home field is nothing in EA's brand of college football.
-A pre-game show for big games with fans cheering/booing based on Lee's picks.
-More cutscenes of fans, cheerleaders, coaches, players...the whole shebang.
-Schools should feel different. Right now, all big time programs feel the same and all small time programs do too. Playing with USC should be different than playing with Ohio State, or Michigan, etc. Find some signature chants, school themes, etc to heighten this.
-In that same vein, Rivalries should be loud, intense, and have a bigger sense of fervency as a whole.
-Punch up the commentary. Not enough excitement in the voices and it's gotten stale over the years. There should be team specific and situation specific commentary for really big moments. A bowl game should not be called with the same nonchalant tone that most other games are...same goes for rivalry games and ranked games to varying degrees.
Presentation is sorely lacking in this game, IMO. Just adding some of these things would help immensely.
