Can you put a CD ROM game on more than one computer

for that you need to read your "EULA"(End User License Agreement) is what you usuallly agree without reading when you install the game or contact the company who made the game, usually you are only allowed to use the game CD in only ONE(1) computer unless you pay to the company or if they send you by written any agreement saying that you can use the CD in more than one PC, companies usually insert some sort of software protection to avoid that.
