People who pirate games will always find a way to.. Well, pirate games. Some games who are single player only, for example, will tell you that you need an active internet connection at all times. That's about as annoying as having a crapload of zits.
If you really want to fight piracy, and make people invest in something they truly think is worth the price, you should be making better games.
Ghost Recon Online producer Sébastien Arnoult says that free-to-play games are a response to piracy – and an alternative to the restrictive DRM that’s annoyed PC gamers in so many recent Ubisoft games.
“We are giving away most of the content for free because there’s no barrier to entry. To the users that are traditionally playing the game by getting it through Pirate Bay, we said, ‘Okay, go ahead guys. This is what you’re asking for. We’ve listened to you – we’re giving you this experience. It’s easy to download, there’s no DRM that will pollute your experience.’”
