N64 makes first post-launch Wii presence with Mario.
...the first Nintendo 64 game available for the online store since the console's debut more than two months ago.
The article is accurate. Super Mario 64 was a launch title. Mario Kart 64 is the first N64 game since then.
It's pretty ambiguous and should be reworded atleast then. I can see both sides of the argument. It's not like Mario was released before the Wii, so ofcourse it's post release. Meh minor detail, but still kind of tricky.
