There's probably an age demographic involved here. It's probably not worth your time because you're an adult and earn a good income. But most kids under a certain age don't have a job, don't think of their time in monetary terms, and might find collecting and trading cards to be fun.
Steam probably has a ton of such demographic information that would make for some really interesting articles and research.
