Lol at people saying a game world would be bigger due to system processing power. Completely silly. You could make a massive world on NES if you wanted to.

OT: I would expect XCX to have the bigger world because that's what they do. FF has never been about that in the same way.

xenoblade choricles is bigger than any FF game and X will be 5x the size..my vote goes to X.

Xenoblade will be bigger. I only plan on buying one of these games and it's not FF.

My vote goes to Xenoblade Chronicles X being bigger since it's improving upon the original. Final Fantasy 15 does look big for a Final Fantasy game though, so it should be interesting so see how that turns out. I wonder which of the two games will come out first.

Xenoblade X will be bigger,and way more interesting of a place to explore.

Xenoblade. Unless FFXV comes in 69 super quintiple layered 1337 yottabytes blu-ray discs. Then it will be almost as big.

I would have said Xenoblade, however, the fact that you literally have to drive in between places with FFXV and that you can get out and explore the area, gives me the opinion that FFXV might in fact have a larger area.

Xenoblade Chronicles X for sure. Final Fantasy XV will be much more detailed obviously, but that will ultimately be the reason the size of their world to be smaller.

Both look huge open world to me, which one is the bigger one is irrelevant. A lot of people were craving for an open world JRPG for next gen so there you have it, two games to choose.

I'm hoping Xenoblade X has a world that's worth exploring. The first title had some nice locations but a majority of the game was just barren stretches of scenery with little to no purpose.
