Was waiting for this, but can someone explain why Metal Gear Solid isn't on PS Now?
PS3 is the only place that can play all the Metal Gear games... They even made a huge collection with all the games (without MGS V of course).
That said, there's still enough value for a few months. Games like Motorstorm, Resistance, Ratched & Clanck , Infamous, Killzone and Sly collections alone are worth playing.
It's a pretty good list and for the people without a PS4, I see it as a must to play the Naughty Dog games.
If this works well, you could easily see why this is going to be important for gaming in the (far) future. They could easily make Uncharted 4 streamable at some point.
