I found the immersion of Xenoblade was broken on wii u when you walked through objects and also when they appeared close to you out of nowhere. It seemed like an engine too ambitious for the console. I have to say I understand its the same resolution but it looks better and the collision detection and other features look more advanced. It just looks beautiful and much better. I'd rather have this than a 900p or 1080p version that looked and played like the wii u version to be honest. Hopefully there will be improvements but to me it just looks like a much more solid engine that won't break the immersion in the same way as Xenoblade on the wii u and that to me is a huge win.
I just wish I'd enjoyed the games more, I adore the world's monolith create but don't enjoy the gameplay mechanics as much. I still enjoy them don't get me wrong but just not as much as others I feel.
