Square Enix has a new trailer ready for your consumption, and after playing the Final Fantasy XIII-2 demo, this time travel teaser is very interesting. 

While it's unlikely that the mechanic will let us affect the worlds in any other Final Fantasy game, it's nice to dream, isn't it?

Either way, it looks like it could be a nice surprise element when the game releases on January 31st. 

Is there anybody else out there who is very intrigued about this new game mechanic?
