Just a random thought, I have e-reader games, but don't personally think each one should have a case. I think it's a waste, so I was wondering if people wouldn't mind a "themed" case. Like 3 card sets per case, with each having a certain theme. For example, there are 3 Donkey kong themed games, so that could be one "Donkey Kong Series" case, 3 sports games could be a "Sports Series", and so on. Again, just a thought since I have limited shelf space.
