How Valve experiments with the economics of video games - GeekWire
Matt Nunogawa stashed this in Pricing
Consumers value "free" and "free-to-play" differently:
The most recent thing that also is really puzzling is that we made products available for free on numerous occasions, without significantly impacting the audience size. We recently said, we’re now going to do something different, we’re not only going to signal that it’s free but we’re going to say, ‘it’s free to play,’ which is not really a pricing signal, even though that’s what you would ordinarily think it is. And our user base for our first product that we made free to play, Team Fortress 2, increased by a factor of five. That doesn’t make sense if you’re trying to think of it purely as a pricing phenomenon.
Why is free and free to play so different? Well then you have to start thinking about how value creation actually occurs, and what it is that people are valuing, and what the statement that something is free to play implies about the future value of the experience that they’re going to have.
