I think jumping puzzles would be really cool to add, I believe Yoshi has been quoted as saying he would have liked to add them in if he had 6 months more dev time before release as well...

I would just love for the different areas to have more depth in all honesty, cave systems, perhaps rafts/canoes to traverse rivers and lakes, special areas that require a chocobo's jump (maybe to come from raising/racing as a special ability)

I would like to hear what other people think about this, and hopefully spark some conversation about how others would want to Expand Eorzea?
