Research Paper Thesis

For my research paper i have decided to search and write about video games.I am not a big video game myself and i do not understand why people decide to spend so much of their time on video games and not other things.Well maybe its because i never really played much of them to understand what the fuss is all about.My brother is a huge fan of video games, he spends so much of his time playing them that one would think he is an addict.I am worried about him and other people that may be addicted to video games.They do not want to confess that they are but i wonder whether violent video games have a positive or negative influence.
My thesis is still in the making but here is what i have so far. Are Violent Video Games to blame for Teenage Agression and Bad Behavior? or something like that.I am excited to be working on this paper and have already started as i look for sources i come up with a different thesis each time, but this is what i have so far and im excited to hear what the researchers have said about this!
