epics
•place a lot of the focus on character development and how the character grows throughout the poem

romance
•the main focus of the poem is not on the character but rather on the Adventure itself
•the protagonist in a romance is more static, usually concerned only of a single group, family, or class (ex:a knight of the round table)

•romances tend to have happy ending and everything tends to fall into place at last moment
