With the team largely built, they needed to figure out how to make a game centered around authenticity. That meant everything: stadiums, rosters, mascots and crowds.
The team created a pageantry database, which became a rolling list of traditions and idiosyncrasies for all 134 FBS programs. They asked schools for help, added what they knew from their own college football fandoms and even scoured fan forums to find things they may have missed -- or to learn that a school no longer did tradition X or hand signal Y.
Production director Christian McLeod said every school had to have something. Not every tradition or chant or hand signal ended up in this year's game, but they wanted something for everyone.
"We want to make sure that, again, everybody's team is somebody's favorite," McLeod said. "Texas and Texas State need to feel the same when you're playing as them if you're a fan of that school."
Building this took time. In all, EA Sports received tens of thousands of assets from schools in addition to their own work. They asked for and compiled touchdown celebrations for each team and stadium, how players celebrate after turnovers, how teams run out of tunnels, crowd hand signals, chants on key downs and details for stadiums, mascots, cheerleaders and uniforms.
