More and more I'm thinking that preference of one style over the other is a personality thing. The way you have to think about player facing games reminds me of the way actors talk about their craft. It takes a different mindset than most of us have(much more left brained). That also would jive with the difference in the number of DM facing games vs. the number of player facing games. Just like there are a lot more of the rest of than people who are actors(or think like actors), there are a lot more DM facing games out there.
That's not to say that people can't enjoy both, but I think the preference for one over the other is going to go hand in hand with how people think and perceive the world.
I've found that the vast majority of people are quite capable of enjoying either, when they are done well. Most players have been trained by D&D, which has really never escaped its roots entirely. They come pre-educated with the very thought pattern [MENTION=29398]Lanefan[/MENTION] was using there. It takes some time and familiarity to unlearn and realize that the Story Now game is a much more open book.
OTOH Children almost invariably attempt to play Story Now. Often the adults try to reign them in, but in fact they are excellent players. The uninitiated of all ages in fact often do this, they attempt to enact their vision of where things should go and how the world works. Typically they get 'taught' to follow someone else's lead. I think you could also say this is something that arises from general socialization. Independence of thought is not encouraged in this world.
