Splatoon

[Vipershark]

I didn't watch the chat during the stream so I don't know what happened there but the overwhelming majority of things I've seen about Splatoon (here and elsewhere) were extremely positive.
For a lot of people it was like "okay, I can get a Wii U now" (plus several other games, you know, but still)
The sheer amount of fanart within the first two days alone was crazy. Thousands of images just immediately popping up with people showing support.
