OP, you should test your Internet connection on speedtest.net. Give the results here.
So far you are still the only person with any major connection problems. If your connection is 7mbps or 7Mb/s then it might be time to consider upgrading, that's hardly usable for many online applications, especially gaming, plus you might be having ping issues. Do you use wireless? If it is indeed 7MB, that should be fine since it's roughly 56mbps, but that is an odd number from an is as they generally use mbps and use round numbers.
As far as motion controls are concerned, some will like them, others will not, it's moot since it can be changed so it really should be removed from the original post.
Nintendo fans are more than willing to be critical of their games just as any fan is, but there are also others on all fronts that are not willing to say anything bad about their system of choice.
Gotta figure out how to set these up lol.
