Exactly. I mean honestly you can read a comic book or two in maybe what? 10-15 minutes, lot less time than it takes to play a video game. Hell I can read part of a comic during loading screens on Guitar Hero! BUT I think both can be kinda geeky, video gamers can be really geeky if you let them. I mean who ever heard of someone sitting in a room all day and all night just reading comic books, without a break, peeing in a soda bottle, hopped up on Red Bull or Mountain Dew Game Fuel.? Not many. You can waste HOURS on a video game... comics... not so much.
And let's think about it somewhat logically... comics are exercising more intellectual parts of the brain. Specifically the reading and comprehension sides, as well as stimulating the creative sides with the art work. A good comic will stick with you. But will you remember the last "mission" on a video game ?
Both are geeky and both can be obessive, but I think video gamers can get scarier!
