My suggestion is to send the whole staff on a field trip to another big-time college game, say UT or or Oklahoma, and get ideas from them. I'm not talking about traditions, but gametime experience - how security greets you at the gate, what you are and are not allowed to bring into the stadium, audio and visual from the scoreboard, the way advertisements are delivered (i.e. do other schools read ads over the PA system? I know that U. of Washington does not), canned vs. live music (i.e. what type and when it is played), etc.
Make the experience as enjoyable as it is to attend other games. People shouldn't be taking home memories of how the game experience sucked, they should be taking home memories of how the game itself sucked.
