After reading this amusing Preview about FFXIII (WARNING THERE ARE A FEW SPOILERS!!!) as well as my own personal discussions on the nature of linear game design, I've come to whimsical conclusion we at EoFF should seriously sit back and ask ourselves what actually constitutes an RPG? What are the defining guidelines that keeps a game in the RPG genre and doesn't just make it an interactive movie with a menu based system or in term of action RPGs, doesn't accidentally transform it into an Action Game itself.
I just feel that in the modern age, defining RPGs as simply a game with a focus on storytelling is kinda silly cause most games now feature a heavier emphasis on storytelling. DMC4's greatest criticism was how awful the plot was but if this was fifteen years ago, such a criticism would not even be an issue cause action games were not designed to be about storyline, plots in an action game were just a semi-logical excuse to explain why you are shooting aliens with your six shooter while riding a dinosaur. Obviously things have changed and games like MGS, SotN, and RE have made strong narratives a mainstay for action games so now that RPGs (or at least JRPGs) are losing their old school niche, what is left to define them.
XIII has removed towns and old school shops, and transformed most of the dungeons into simple roads, NPC are almost non-existent and the world and flow of the game is heavily linear and offers zero choice. I feel the question many critics have been asking, is it still an RPG? and why? What defining elements does it possess that makes it separate from other genres? What's to keep people from saying its just a menu based action game? I mean we've reached a point now where other genres have been sampling the RPG pie so much that it is hard to say what actually constitutes an RPG and not just be one of its many splintered offshoots.
So my question is this: What is your definition of an RPG and what do you think a universal definition for it would be? What do you feel it should be?
