Still have my WiiU copy and accidentally (Literally) bought two copies of Xenoblade Chronicles X for Switch.
I forgot I pre-ordered and bought the game online months ago... And so I went down to the games store, picked up a copy on release day... Then to my shock had the other copy rock up on my doorstep the next day.
I like the games, but subconsciously more than I thought.
Being able to compare the games in real time, the Youtube comparison Digital Foundry put up doesn't really do the jump justice.
It is probably one of the best WiiU to Switch ports we have had... It's more than just an up-res.
The only niggle I have is still the pop-in from objects and characters, but that's an engine limitation not a Switch limitation.
