Yeah, I got a wii U game fairly recently and panicked when I fired it up because it wanted to access the internet to look for updates. Luckily you could just skip past that and still play, but it made me wonder about the newer games that are just download codes and how they will be handled. Though I already have a good guess.

It's annoying enough that they didn't patch either the systems or games to not bother trying connecting to servers that no longer exist. Though now I'm wondering if anyone cooked up some home brew servers they can redirect DNS to that at least say "connection accepted, nothing new here, grey out the options that depend on this being real" if not attempt to support actual features.
