I think you are all missing the point and are skirting around the answer even though it has been said. Neither RTwP or Turn-based mechanics have anything to do with whether a game sells well or makes a good game. It is the story. If the story isn't done well then it doesn't matter what mechanics you have, what computer you use, the size of your graphics card, or whether you live in a luxurious mansion or your mother's basement. (sorry had a Tommy Lee Jones moment.
)
If the story isn't good, word of mouth will rule the day. The same applies if the story is good.
People fight against change or for what they believe. RTwP or TB?
Remember when the earth was flat?
