Tag alias: wii -> nintendo_wii

wii -> nintendo_wii

to maintain uniformity with the other nintendo_* tags

But the Wii's name is just "Wii". That's how it's used on the official website, Wikipedia, and most other places.

The Nintendo DS and Nintendo 64 actually have "Nintendo" as part of their name, the Wii does not.

hmmm true, I hadn't thought about that
