Piracy

[kee nethery]

The software authors who make the most money focus more time on  
getting people to use their software and getting their friends to use  
their software than the time they spend preventing people from using  
their software.

That said, you have to profile your typical customer. If you produce  
a game that is used by the younger crowd (action shoot'em up), you'll  
need lots of protection because breaking protections and sharing  
codes is part of the game for them. If you produce a game for the  
older crowd (solitaire, poker), they just want to play the game to  
it's fullest and make sure they can get updates and support, they  
don't typically share keys.

Some of the more successful software has had some of the lamest  
protection because their user base (the one that is going to pay)  
values the connection to the developer that paying gets them.
