Everytime i have talked with an american, they always seem to be interested in Sci Fi. Someone reads Sci Fi, someone watches Sci Fi, and somebody plays Sci Fi game. But then again i did like Mass Effect.
But they also have a show called "Star Trek", which i think is geeky, i have never watched it, but its quite popular.
Just curious, i am more interested in nature and stuff like that though, i guess i like flesh and trees more than space :P
