Well.. the idea that Nintendo has online gaming is debatable at this point.. ;p
Haha true. If they tried to charge for online gaming very few people would even notice. The fact that they still don't have online infrastructure as good as what Xbox Live launched with on the original Xbox in 2002 is ridiculous. They still don't get it. It's a bit ironic that the company that made motion controls a thing still thinks that online gaming is a fad.
Also, I don't own a Wii U but they really need to get with the cross buy trend for virtual console games too. If you buy a 20 year old game on your 3DS you shouldn't have to buy it again to play it on your Wii U. I think downloadable games are still tied to the system instead of your account too. I prefer my games in downloadable form on the Vita but buying the carts makes more sense on the 3DS. I'm pretty sure that if my 3DS was lost or stolen I would have no way to download my games again on a replacement 3DS. These are all simple fixes that the other systems have had down for years.
