Awesome! Both are great games to play back-to-back as I think they complement each-other well. Xenoblade Chronicles has a large-scale world while Skyward Sword has a condensed, yet still interesting, one. 

Which one do you I should go for first?

It really is strange that there are still quite a few great Wii games in my backlog. I have to clear them up soon Wii was such a great console!

With Xenoblade Chronicles X releasing sooner than Zelda U you might want to play Xenoblade Chronicles first (both Wii games are pretty long, Xenoblade Chronicles is significantly longer.) X is not a sequel to Chronicles, but if you like Chronicles it should give you an idea whether or not you'll like X. 

Skyward Sword will probably make you appreciate what they're trying to do with Zelda U. It seems like they took the criticisms people had for SS and made that into the Wii U game. 

While the Wii had large droughts (much larger than Wii U's it seems to me), in retrospect, the console was excellent. So many unique experiences and some of the games were not only good, but exceptional. 

By the way, if you have a gaming PC I recommend trying out Dolphin to play the Wii games. Xenoblade Chronicles has an HD texture pack that makes the experience even more awesome, and Skyward Sword looks gorgeous in HD. Both games run at full speed with no glitches  if you have an i5  or i7 that is > 3.5 Ghz. 

Wow. Just wow. So I guess this is actually THE version to play? Better than either Wii or N3DS?

If you have the capabilities then, yes, it is the version to play. I originally played the game on my Wii for my first two play throughs. This third playthrough I played half-way on Wii and then switched to Dolphin when I got my PC built. I'm trying to do a 100% completion run this time and the game looks great at 1080p 4xSSAA with texture packs. There is not a single jaggy in sight and it runs at a locked 30fps with few drops after the shader cache builds up (the first time you start a game in Dolphin shaders need to be built - each time you start the game afterwards performance smooths out, having an SSD helps with this as well.) 

I plan to build a gaming PC with an i5 CPU this year (I've decided to go PC + Wii U this gen and pick up PS4/Xbone near the end of the gen for a few peanuts), so I should be able to run it nicely. So, to play it I need an ISO of the game and a texture pack. I even read that it supports Xbox gamepads... Awesome! So I guess I know which version to play Thanks so much!!

Yeah if you install homebrew onto your Wii you can rip an ISO off discs of games you've bought, or you can just play the disc inside your PC's disc drive (wouldn't recommend, slower load times than off the HDD/SSD.) 

I'd recommend an i5 4690k.

At its base clock (with turbo-boost to 3.9 Ghz, since you only need two cores) it should run the game at full-speed. But if you find that there are some drops it is overclockable (and it's very easy to overclock to something like 4.5 Ghz.) It is by far the best processor for Dolphin because of its high instructions per cycle and also its high clock-rates. Dolphin currently only uses three cores at most (two for game, one dedicated to sound) so you won't find any benefits from an i7. 

This also happens to be an excellent processor for PC gaming too. 

Xenoblade is the best game released in the 7:th gen.

Nothing comes even close.

The story is everything but cliche

I'm thinking about this one. I guess I'm gonna wait till September, when Intel is supposed to release a new gen of CPUs. Maybe I'll manage to get a nice deal on this one

I've been wanting to play the game for a while now, but the copies are so expensive :/

Hope you will keep enjoying the game!
