I want to buy the following games:
Mirrors edge
Gears of war
Need for speed:undercover
Resident evil 4
Left 4 dead
Crysis
Crysis:warhead
Assassins creed
GTA 4
1 month ago I bought Mirrors edge,Gears of war and Need for speed:undercover from BCS Computer City.Firstly none of them run on my Samsung DVD drive.It didn't detect any disk.Than I took it to another persons computer and his drive detected the disks.So I copied them from his computer on a hard disk.After that from that hard disk I copied the files on my pc.But I could not install any of the games.When I start installing Mirrors edge it tries to install Physx and suddenly shows that the Physx file is corrupted and the install can't be continued.Gears of war and Need for speed:undercover starts showing error messages while installing.On the messages there were options for Abort,Retry and Ignore.Retry didn't work so Ignored but at a point it didn't work anymore and the installation couldn't be done.Now I want to buy new copies of these games.The disks of these games were writed disks.Now where can I find good disks like Silver Disk of these games.Many of you have played these games,where did you bought your copy of the game?Please need help.
