That isn't the case though as its the 1080i/p cut scenes that consume all the data. RPG's can be extremely long and still not take that much room as they usually have fixed camera angles and not a lot of room where you can walk, with a set path even. Take Oblivion for example, that game was extremely massive, way longer then a turn based RPG could ever be. Though it was also only in 720P it rarely had any movie clips at all. Lost Odyssey on the other hand it is in 1080i/p (can't remember) but it had an insanely high amount of movie clips just like Final Fantasy XIII did. I remember just some of the teaser clips were like 1 to 2 minutes yet to download them from Xbox live it was like 200MB just for that one clip, so if you really think about it in that perspective as a video clip as small as that taking 200MB and how many movie clips there are in each of those RPG games, then its pretty easy to tell that the movie clips just consume the data and not really the gameplay/story/length/content.
