Well college is different from high school in that we do not have the same class everyday so we do not necessarily have to keep up. And there are lots of reading and for some classes the HW isn't even mandatory. it's just that you have to keep up because it is impossible when you fall behind.
I know that if I start playing GBA games, I will have a hard time keeping up because I will get addicted... That is the main reason why I won't be able to play.
BTW ever thought of making Professor Oak more useful and have it so he can take your pokemon? That is how they do it in the anime... or your mother can take it?
It might be hard as scripting might make that impossible, but it is a suggestion
