Been saying it for years - there is too much focus on the suits and not enough focus on the general community. This type of stuff would be a hit with the general community.
Outside of the Wentz-sponsored giveaways, the marketing is typically quite drab and borderline lazy.
I'd like to see some sort of digital attendance punch card, similar to what you might fight at an ice cream stand. Set up a spot in the lobby or 2nd level where fans can have something scanned on their phone that logs their attendance in a database. Every game attended counts towards rewards.
1 game = Zippy Keychain
3 games = Zippy Plush
5 games = T Shirt
7 games = Hat
etc.
Could also have each game count as an entry towards some sort of grand prize at the end of the season - future season ticket, tickets to the MAC tournament, something like that.
I'd also like to see some sort of Zippy Kids Club brought back.
