Best part is, GGP was most likely a sarcastic remark. A tongue in cheek reference to the fact that valve has talked about a mass-produced Steambox for years now, yet nothing has hit the market.
And isn't likely to happen in the near future, either, considering that they basically canned their entire hardware department for over a corporate culture conflict.
If you want to make a damned movie, get in the movie business! If you want to make GAMES then make them FUN!
There's nothing inherently wrong with cinematic games, though. Compare a snore-fest like LA Noire to the Mass Effect series. Both are very cinematic, but in Mass Effect, what you're doing feels like it matters. you're having fun because you're playing it. LA Noire was a barely-interactive 20 hour movie which ground onward inevitably with or without you.
The problem with the Wii was never that it didn't play DVDs. The problem was that its catalog of games was lousy. Seriously, look at which games are still selling at full price, and which dropped like a rock two weeks after release. Hint: Twilight Princess is still one of the top-selling Wii games... and it was a GameCube game. They won't get anywhere without developer support.
Okay, I will admit, they rewrote the book on hype and mass-marketing, this generation. That, combined with actually making a profit on hardware sales, put them solidly in the black. I'm not sure the "Nintendo iPad" will manage the same feat, though. That controller is going to cost a pretty penny.
It occurs to me after the fact that I should have probably been searching torrents instead of looking for a download from a website. Indeed, that search takes all of five seconds to bear fruit.
