Nice idea and I wish you good luck for the paper! Only point I'd specify is the term "role-playing games". I know you probably will focus on die-hard RPGs with health and magic points like Final Fantasy but therefore you probably will leave out "action-adventures" like Zelda (which features great music
).
Also you left out the N64, but as it has not very much RPGs you could just ignore it.
