DRM whether it is in games, apps or the OS itself simply alienates the user and has been shown time and again not to protect against large scale piracy. It might deter Joe Average from installing his game again on his brother John's PC and playing against him over the LAN but it won't affect organised pirates. Really it's just a waste of time and money. The games developer gains little or nothing from it and the licensed gamer loses out every time and is treated as a potential criminal from the start. It is only the developer of this junk sofware that rakes in the profits and goes laughing all the way to the bank.
