I love to watch trailers,but that doesn't influence my choice when purchasing games. I feel that some game trailers are highly exaggerated,and therefore I prefer to play the demo to get the feel of the game.
I think gaming addiction is more prone to people who are at a younger age. Therefore, when they are grown,they are still deeply rooted to their games. To avoid this addiction, parents should limit the frequency in which their children play games.
Losing in games as a child was awful and humiliating.I just couldn't stand losing to a friend,and what's worse was the fact that they would rub it in your face. They still do.
