Unfortunately, many people look at the games as a waste of time. The question in their minds would be, "Am I here to play games or build a business?" In reality, playing the games will help them build a business because of the prizes involved. Not only that, but the games are a nice break from working so we don't have to be "All work and no play."
Chances are, many people are already play games during the day so why not win some great prizes while playing?
