You just need to go onto the San Andreas website - click on PC and find a place which will sell you the game. They're in stock. All games downloaded onto your harddrive will not have viruses.
The only way you can get viruses is by downloading illegally. rockstargames.com/sanandreas/pc.
You can get the psx version for use with an emulator from cool-rom.com for free.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
