I read the whole "Grand List". It was pretty true for the most part. The list Soriku posted was more about cliches that make the games less interesting. I hated random battles so much. I think that's why FFVI is not my favorite game of all time.
While it's true a lot of RPGs heroes are teenagers, the same could be said for a lot of popular movies and books. Harry Potter is a teen, I think Luke Skywalker is a young adult, etc.
How many cups of darkness have I drank over the years? Even I don't know...
