I've linked this on Twitter, but I wanted to post it here to make sure I can get as many people to see it as possible.
Whenever a sales report comes out that shows Nintendo isn't doing so well with their Wii U, I think about this video. Gamers everywhere shout "WE WANT NEW STUFF!" then when Nintendo gives us something new, gamers shout "THAT'S TOO DIFFERENT! WE WANT THE SAME STUFF!"
This video explores the subject better than I can, so I won't rant any more. Just watch it. Let me know what you think.
