I'm trying to write an introduction to my paragraph can you help,does this make sense?

Many may think that letting teens play violent role-playing games has little to no effect on their behavior. What many don’t know though, are negative impacts on the lives of teens when allowed to play violent role-playing games. Parents who let their kids play video games wonder why their kids aren’t the top at their school. Teens should not be able to play violent role-playing games because students are forced to pay money, they put teens under unnecessary pressure, and they encourage them to take dangerous risks which is illustrated in “High Jinks:Shoot-Out”.

I think, first, you should explain clearly what the negative impacts are. Do grades suffer? Is the cost of playing the games a bad thing? What unnecessary pressure, to do what? The only clear statement is that such games encourage teens to take dangerous risks.

That might take more than one paragraph. But a topic sentence states the point of the paragraph: violent role playing games are bad or teenagers.
is this better?
