CD Projekt RED, developers of The Witcher 2, told VG247 that DLC should be seen as a means of fan-service and not a way of monetary gain.
“If today’s DLCs offered the same amount of content they would be worth paying for, but in most cases players think they are overcharged for what they receive. That’s why we offer expansions to our game for free. This is also a way of saying “thank you” to the people who decided to buy our game instead of copying it from an unauthorised source.”
