Here is the story: I played an unhealthy amount of computer games in high school. I made mediocre grades in high school and my skill at Starcraft was still lackluster. I decided school was more important so I quit video games altogether.
If I am going to do something, I want to be the best at it. Currently I put my efforts into being the best student (my grades show). With the release of SC2 I really want to play, but there's no point in playing if I'm not the best. This leaves me with the solution of dedicating an entire semester to developing my Starcraft prowess.
When SC2 comes out, I'll play approximately 7-8 hours a day like a normal job and still have a social life outside of swarming my enemies with Zerglings. Really, skill at this game (or most any game) is commensurate to time spent playing.
This will be a sort of 5 month tour of Starcraft 2; a recrudescence of my high school Starcraft fever. I will register for classes in the subsequent semester.
