I want to be a game developing writer.

My long time dream that i'm working on is entering the games industry, and build up computer games.
I'm talking on being conceptual creator (characters, units, plot act), not a programmer.
does anyone know if there is a need of any academic knowledge, and what kind of, to be on my resume?
what kind of skills do i need except for overdeveloped imagination and creativity to get into the large companies in this field?
