There isn't anything that the Xenoblade on Wii does that Xenoblade Chronicles X doesn't do bigger and better.
XCX has a superior world, a superior story, superior characters, superior gameplay, and is just a much more interesting game.
Most importantly, XCX actually feels like a Xenogame, whereas Xenoblade on Wii was more like a really slow paced Saturday morning children's cartoon.
I describe myself as a little dose of toxic masculinity.
