Some computers have a built in dvd player but if you don't you need to buy a blu ray player and attach it to your computer.
ps3 games are bluray disc
key phrase "game you can ONLY play on a pc" this implies you need a PC.
You need the disc for PC games.
No the disc is for the PS3 only to play the game on a PC you need to purchase the PC game for Call of Duty Black Ops
no, but only on PC you can mod.
PS3 games do not play on PC even if the Disc is the type your PC can read and not a Blue ray disc
yes or a game download
you need to go somethere like PC world and buy a disc you install
Read my answer under the question How do you play a PC game without the disc in the disc drive? on this site.
You need to have the game disc or download and a platform or PC
On a PC you need the game disc or PC download and Windows Vista or XP
OK, I'm presuming the disc has broke, when you've got them all on your computer?If so, do you mean the normal disc as in the Sims 2?No, you don't need the deluxe disc to install the normal disk, but you will need to un-install it from your PC, otherwise it'll get confused.
