Never played the first one, but really digging XC2. There is talk of XC and XCX collection hitting the Switch and I will definitely pick that up.
I picked up Xenoblade Chronicles X for the Wii U, but it came out smashed between Fallout 4 and Dark Souls 3 and it honestly didn't get the attention it deserved. I tried to get going after I was done with FO4 knowing I would drop it in a few weeks once DS3 hit. It has a pretty in depth combat system and I knew I wouldn't get very far in a few weeks so I decided to drop it and just wait for DS3.
The Combat in XC2 is close to X, but it has all of my focus so I've gotten most of it figured out and loving it.
