Final Fantasy games for me have been mostly about the story. It's what I enjoyed most out of the multiple experiences. In a new age though it's hard to keep peoples attention with plain text. Take World of Warcraft for example... In the 5-6 years it's been out I don't think I've ever read a complete quest when an NPC as given it to me. I know tons of people that don't pay attention to the quests which could be a massive part of the story.
A problem that Final Fantasy 14 is that the story telling is not very good. I recently started playing Star Wars: The Old Republic and I was amazed to find myself wanting to finish every single quest dialog that I came across because of three reasons. They are fully voiced, cinematic and interactive.
I know SE adding something like this is a bit of a long shot but mixing this kind of system with Final Fantasy seems like it would be so amazing!
