I play games 20+ hours a week, but I'd say over half of it is with real-life friends, often in the same house. I can see how playing games a lot can be potentially harmful, but I think a lot of it has to deal with the individual. While I've logged tons of hours into my xbox 360 (nearly 60k gamerscore), I've kept all of my friends the entire time, made plenty of new ones, and always had a girlfriend. I've also done very well in college, played sports, etc. Basically, what I"m trying to say is dividing the line at 20 hours a week seems kinda ridiculous to me. So once again, this kind of study should be taking cautiously. Granted, if you mostly only talk to your guild mates on the phone about a new WoW raid or something, you probably have a problem (not hating on MMOs or anything).
Yes, because tiny differences in graphics matter at all. Oh, and Sony fanboys..keep saying "You just wait till next year!". Pretty soon that'll be "Just wait till the PS4!" Accept it, most cross-platform games are developed for the 360 because the tools are harder for PS3, and more expensive.
