Who was in disagreement with adding swimming/underwater content, made a sarcastic comment about why not to add moon content?

So yeah, why not?!!

Lol no but seriously... how do you guys think about having some kind of FF XII technology. I always liked how Final Fantasy could blend Medieval/Fantasy themes with Futuristic technologies.

Look at FF VI, FFX, FF XII ... i may be forgetting other examples.

How about a high-tech city with FFXII style technology? Or with FF VI style steampunk tech.

It could also open the door to new crafting classes.
