You should only play Xenoblade Chronicles Wii, it is a much better JRPG in every aspect. If you like the genre, you will love this game and it may become your all time favorite game on any system. Best way to play is in 1080p on Dolphin Emulator, 2nd best way is Wii-U VC.

Xenoblade X however in my opinion is not really worth playing (I wasted over 100 hours), it is not even a real JRPG and feels more like some kind of dungeon crawler without dungeons but with mechs and a very bad and extremely short main story. It takes all the bad but optional fetch quests from Xenoblade and makes them mandatory. It also limits your party choices and once a mission is started, you are locked out from the rest of the game until you complete it. And it offers nothing besides the main city, all the continents are empty and lifeless, there is not a single town or city to explore.
