Anyone who has had the pleasure of playing against a wifi warrior already understands that streaming a game+connecting to a server that both of you are in order to play is asking too much.
Unfortunately, from what I understand, while everyone knew it was coming, the timing was a surprise--it'd be like panels 2/4 didn't exist, and 6 was someone putting a peel under Angie's foot as she stepped down. Like, people signing contracts very recently, and with post close release dates already.
The internet is abysmally regulated in the US, so many couldn't even get close to being able to stream games. The whole idea of paying for membership just to pay for the games was a joke... And let's face it, trying to game on your phone without a controller sucks.
I'd say "oh noez", but did it even really deserve that much sorrow? It was an interesting concept, but it had some *massive* hurdles it didn't even begin to overcome.
Stadia was packaged wrong. Wong price points. Google over valued its service. Nobody wants to pay a huge subscription fee and then pay full price for games to play on a virtual console. It has some benefits, sure. Not enough to make what is being offered palatable.
