I think that online games like MMORPGs are the worst invention ever. (Generalization of my idea) They destroy kids abilities to socially interact with people in real life when they start playing them too much. It will eventually breed a generation of introverts and I'm afraid that mankind will begin to emulate that lifestlye of living in luxury while living in a fantasy world. I honestly believe that we could become like the people in "Wall-E". Fat slobs on hoverchairs, playing our videogames. There are always exceptions, but I don't like the trend of more people becoming centered on computers, tablets, and games like this. Society as a whole is changing due to some of these factors and I don't like it. Read a book. Play outside. Talk to a girl. C'mon man.
I don't think that's very controvertial, but I agree. I used to play some WoW a few years ago, and I wish I hadn't, the game is lame and has NO value at ALL. It just plays on the human mind to be good at something, and you get validation for that all the time in WoW, like new weapons, leveling up etc etc.
I used to play Runescape for hours on end (I think I have 56 days totaled up with two 99s). I quickly learned that I had to stop playing when my relationship with my girlfriend was heavily lacking communication.
