There's a big difference between game streaming and video streaming, that's the big problem we have: buffering. To talk about that, we will first define how connection work nowadays. They are pretty fast (way more than the mininum), but a bit unstable, so it can oscilatte a bit during a few seconds or miliseconds.

A video is fixed, predictable. So, if your connection can download the video faster than you can watch it (which is easy), the site/player will store a part of the upcoming video content so, when your connection hangs a bit, you won' notice, because the video is already downloaded. If you lost connection, it would most likely take a few minutes to consume the entire buffer and stop the video.

A game is not predictable (ok, cutscenes are, but when you're actually gaming it isn't). So you can't have a buffer for that. This means that any oscilation in your connection/network/router/etc will be instantly noticed.

The second big difference is that you actually have to interact with the game. This means that your input must be sent to the remote server/console, it must be registered, the game must be updated, the image must be rendered and then the image is sent to you. This adds a level of input lag that's hard to solve.

Solutions:

First problem - Internet and network connections/equipments must evolve to the point where they only oscilatte for no more than a few miliseconds.

Second problem - Faster connections help. But there's a physics problem (the speed that data can travel from your console to servers). The solution for the latter is to have the servers as close to your physical location as possible, like servers per country or even state.

While the second one can be solved with today's tech, the first one really can't. It's not  This means that it will take a while until streaming replaces consoles or gaming PCs. But, we like it or not, someday streaming will provide an experience similar to consoles/PCs. Then, streaming will become the norm of the market. For now, they are just testing the waters and improving stuff to reach that level of performance.

Too bad I cannot get PS Now. My AT&T Internet connection is not 5 mbps.

Sony needs to makes PS Now Games available for download like Xbox Game Pass. And $9.99 a month like it, too.

Agree with everything, especially the bolded.

Killzone ShadowFall would be a 9+ game if reviewers played the MP.

I am sure many did. The only reason I said 

"Didn't someone say ps4 exclusives will not be on psnow until next gen?"

Was because when I said exclusives were going to come when Sony announced ps4 games coming to psnow, they called me an idiot and said it would never happen until the ps5.

For this month? Game Pass is a service that gives you access to the entire library of games. It's not like PS+ or Games with Gold, where you have to be signed up every month or lose out on new additions.

It's closer to PSNOW, the difference being it isn't streamed.

I confused it with Games with Gold. So, it's like netflix? Such a concept should have taken off rapidly but I guess without the library to back it people aren't interested.

It has quite a decent library to start with and it's only £7.99 a month, launched a couple of months ago I think. Hoping it takes off because I would like a similair service on PlayStation.

Well PSNOW is a similair service, but if it allowed you to download the ps4 games you have access to that would be great.

Worth not having a console? The only big exclusive on their right now is Killzone which has been on sale on PS Store for under $5 many times over the last 3 and a half years that it's been out.

If this is going to be the norm for how long it'll take games to be on PS Now then you're definitely better off just buying the console. I mean if you're going to be suscribing monthly then it will already be the price of the console in a year, that's not counting the $50 for the DS4 you will need to use PS Now. Then there's the issue of games rotating in and out of the service so you never know when a might lose access to game you were in the middle of. With how cheap a PS4 console is right now, PS Now is a terrible deal and you're not likely to be playing any of the good exclusives like Uncharted 4, Horizon, God of War, etc. until PS5 is already out.

I honestly can't believe these streaming services exist due to lag. I don't care who's making them. They're just not good enough yet.
