I agree with Boris to some degree. I do believe that because of computer games my younger brother reads less and has less imagination. Now this is my personal opinion and I don't believe that video games cause violence but the more computer games you play the less skillful you will be at reading/writing or anything that you're not doing.
And before you say anything, yes I do play computer games and I would call myself a hardcore gamer but it's all about balancing life. Saying that you can learn reading and writing skills from games is an stupid view that gamers share because you are 'gamers' and don't like anyone saying anything bad about games. Sure there are some games where you solve puzzles but there are also a majority of games where you just shoot things and I'm not saying games should change but I'm saying they do distract people from doing other things which could be more benificial.
