Found a video of someone who did their best measuring the worlds of the Xenoblade series. They meme a bit about XC2 being the biggest if you include the Cloud Sea, but put the real measurements at the end.
Their results, in square kilometers:
- XC1 28.83
- XC2 21.10
- XC3 40.62
- XCX 355.78
That’s including “explorable” water/cloud sea portions for all games, but even if you cut down to just the landmass the XCX map is still around 100 square kilometers… and that’s not counting the parts of the map that have several “layers” like mountains, caves and floating islands.
