Hi,
Welcome to Science Buddies!
You have an interesting idea for a science project, but there are a number of challenges involved in doing a science project on the topic of videio games.. One is that it is difficult to measure the effect of video games and the seconds is that you need approval from the scientific review committee to to a project on humans.
Therefore, I recommend that you use the topic selection wizard from this webiste and look for a project that is quick and does not require a lot of materials, which will take time to assemble. The science fair judges will be looking for a thoughtful experiment with carefully controlled parameters and results that can be measured.
