why must you install games?

i mean you got the disk, so why do you got to install the games... and even after you install them, why do you still have to use the disk?i mean the 360 works fine and you dont got to install games... why must you install games?
most games that are coming out for ps3 have to intall most of the files on to the HDD in order to play it same with pc and u need to the cd to play them just like u need the cd to play on xbox....why must you install games?
1. The 360 was built ONLY for gaming, so i doesnt need to install the certain things the disks have on them.2. The disk is needed so it knows u own the game, and probably helps prevent piracy.3. You install them so it goes inside the computer and so you can save games and such, cause games save on our hard-drives and take memory, so i must be installed into the comp so it can do certain things. i think.
Because a dvd/cd disk is slow as mud compared to a hard drive. The cd in the drive is just a copyright measure, no technical reason to need a drive in the disk on a PC.
Because everyone has a different system config, and it must install it to make it work. With PS3, it jst puts files on the hdd so it doesn't have to search the disc and take forever.
Let's go back to the cartridges shall we?[IMG]http://seoagora.com/img/308/i08r1014muda/cool2.gif[/IMG][IMG]http://seoagora.com/img/459/s08s1028enjy/wink.gif[/IMG]
1)on the PC its usually to prevent piracy and due to the tradition the PCs originally just couldnt hold the amount of data needed to play without the disc so there was some sharing a good example would be the old Warcraft 1 back in 1994, the full game install was 70 Mb, seems tiny now but back then it was huge, this could easily fill up around 20-30% of the average hard drive, so discs still hold some information 2)on the PS3 its usually just to improve performance by not making you have too many loading times. this also applies to PCs as well

PC games could easily be played without having to do a huge install. There would still be at least something, but a big one would not be needed. Some game installs offer minimal installs and will read off the disk while playing. The down side would be having to sit at loading screens while the drive reads a ton of stuff and the CPU decompresses it all. And possibly having to do a ton of disk swapping depending on the game.It's a safe bet to assume that most PC gamers would rather just do one big install and not have to deal with any of those hastles.I personally just go full install all the time since my HDD's are so much faster and have the room for it.
