Square Enix has a very bad habit of showing games way too early. Its latest reveal, Lightning Returns: Final Fantasy XIII, is only thirty percent finished. Meaning? It's 70 percent unfinished. So unless Square Enix works faster than it has in the past, it could be a while before, wait for it, Lightning strikes again.
Until then, let's busy ourselves with reading about Lightning Returns! That game does sound interesting.
During the recent Lightning Returns presentation, Square Enix continually remarked how the game was "World Driven". There was even a slide at the presentation that actually said "World Driven". What does "World Driven" mean? Well, the way you interact with the in-game world affects said in-game world. For example, the world of Lightning Returns is slated to end in 13 days. So, depending on your actions, the game can actually end before those 13 days peter out. According to recent Japanese game magazine leaks, the game builds towards a happy ending to Lightning's saga. (There does, however, seem to be a bad ending if, say, the 13 days run out!)
