Computer Games: Good or Bad?

Obviously, since I'm a teenager, I think that computer games are very important to me, otherwise I would be bored everday of the summer. Once school starts, I probably won't be able to play too much computer, because of the potential massive amounts of homework I could receive.
So, computer games. Are they good or bad?

Pros:
-fun
-kills time in an entertaining way
-some games are educational, like physics games and puzzle games
-it's a good way to be entertained after work
-multiplayer games mean you can play with other friends or play online

Cons:
-too much can hurt your eyes
-not healthy to stay in front of the computer all the time
-may distract you from work
-some games have bad influences
-they can control the way you live

There are probably many more, but I can't think of them right now. Internet games might not refer to only "games", but maybe videos online too. Youtube is definitely important for me, because there are some people online that make really funny and exciting videos that are interesting to watch. People that are very popular on Youtube actually get paid for creating videos. The money isn't little either. It doesn't feel very fair, because the videos online don't look very difficult to make. It's just a bunch of people videotaping themselves and doing stuff. They may have important connections, which helps them promote their online "career".

Overall, I think that computer games are good, but only to an extent. I love Youtube though.
