But how can you protect the game from being used on more than one pc, and from being copied.
This is probably a question every game designer asks ^^
But how can you protect the game from being used on more than one pc
I guess getting the player to input a unique serial number might help, but people can easily share these so really, they are not a very good option. You could get the player to have to verify the serial online, and then the server keeps a track of all 'used' keys and if someone tries to register using a taken key, prevent the installation..
From being copied? If on a disc you could use some sort of copy-protection (SafeDisc, etc). But these two questions are a problem for even major game producers to fix.
