First of all, this trope has gotten itself partly merged with Sports Stories
so it would make sense to make this page a purely non-sport game story genre. (Apologies if I'm not making myself clear). A good percentage of the examples are correct but there's a few sports ones in there. This should really be a sub-trope/sub-genre of it. So all of the Sports Stories
examples need to be moved/destroyed and a better written description to separate them.
Next, there's no reason why it should be just for anime. I've only got six non-anime/manga examples but they still count.
Third, it should be an index. It sounds like a genre, it's in a genre index and there's no real way of classing the examples as anything else so it makes sense to turn it into an index.
I'm not sure what else on this page needs work but that's a start.
