Did you have multiple windows open and mistook this thread for this one:

lol happens to the best of us i guess!

I think you are misunderstanding the part that you are underlining. How much you need to install before starting to play does not mean that the full game will not be installed, and it does requires to install them in full.

The games till now announced, require...

CoD: Ghost: 49GBs

Knack: 35 GBs

Killzone Shadow Fall: 45GBs

Don't know about others, but the average looks like 40GBs per game, so basic PS4 will let you use around 12 games, and then you will start managing your data, and those sizes are without DLC, which can increase the size of the game by a few GBs.

They should just make it so that the part that requires waiting before being able to play never gets deleted automatically but the rest will if more space is needed and the game hasn't been played recently.

In PS3, games would go from 3GB to 15Gb... games are now larger, but people are complaining that they will only be able to install 10 AAA titles... and some people say the PS4 has no games :)

If you care that much about data management on your console, buy a bigger hard disk to begin with, otherwise manage the data... if playing 10 games at once is too big a problem.

This is a non issue, when you consider the Wii-u's minimal disk space, and the Xbox has 500GB and you cannot swap out the disk (yes i know you can install an external disk, but you still have to buy one).

Installing to the hard drive is.

While it is cool to not have to wait to play. I DO NOT like the fact that these games on discs will take up freaking 30-40 freaking gigs of space on average on the hard drive. That is INSANE if you ask me it makes even the 500gigs it comes with seem small when you collect more than 10 games. And 10 games is NOTHING to a gamer heck MOST of us here have WAY more than 10 games. So this is not good for me...I will have to delete data on games just to play new ones and will have to choose what is worth keeping/doing over etc....it just seems lame if you ask me.

That goes for both PS4 AND the XBOX 1....this is all in my opinion though....

THe real lie is that we will have to buy a hard drive.

If the difference between uninstalled and installed is ~10 seconds, why would you ever be worried about redoing installs? So you can save the 10 seconds? IIRC xbros had no problems switching discs last gen, and this gen were floored by how xb1 seamlessly moved from one app to another. PS4 will allow you to seamlessly switch between ~12 games and apps before an install is required.

Xbox fans are really out in numbers today, so much hate. I didn't notice any hate from them when xb1 required installs.
Also funny that xbarros keeps saying "Sony lied" yet he has been proven wrong 3 times already and has yet to reply to those people.

Yeah it's stupid, who in their right mind is complaining that you can play a game quicky without needing to wait for a 15 minute install... I mean some people are looking for issues, they really are. Oh and the irony is that the XboxOne does a similar technique :)

The game is saving part of itself to the system's hard drive. Was also what I was referring to.

But it seems like you're right. The games are caching themselves progressively while you play until they're fully on the HDD. That part, I got wrong. The games do have to be installed because of the limits of the Blu-Ray drive. It's a design choice to make the system be faster. Whatever Superchunk believes.
Now people ask what's the point for discs then? You can uninstall the games once you're done with them, and reinstall them whenever you feel like a nostalgia trek would be nice. Now what happens if it's digital only? You have to wait hours for the game to download again. And depending on your data cap, maybe even pay an extra to your ISP... 

In any case, not a real issue to me. If you'd have to wait until the whole game is installed before playing it, then I'd have an issue with this. But as it stands, I don't play 10 games at the same time, so I don't really care if I have to remove some older games from time to time to make room for newer ones. 

If you're referring to my comment earlier, I was referring to games like Uncharted 2 which don't have 7+min installs but use a cache process. Those caches DO auto-delete. Killzone 3, The Last of Us, GoW3/A all used it as well.
