Steam dosent offer C&C licensed games and i hope EA stays away anyways i believe you buying C&C 3? Dont buy the game from any one else except major stores like target and walmart because some one might have registered the game making it unable to play online

O yeah pick Gamespot cheapest and must trusted wouldn't want you paying then getting nothing so i think cd-keys is a scam they have horrible grammar so i wouldnt trust them

Attention:

Any buer must visit game's offical website and check your PC's hardare. Once find that your PC performance
is weaker than offical request. Pls stop your purchasing.

thank u vevy much,but i have cds ,i only need one key
