p.s. I'd mention Starcraft. but I think I'm way over that now. I kept uninstalling and reinstalling the game over the months... but now I'm finally ready to say that I'm over the game. I said that the summer after my senior year in high school, and my friends even asked me if I still enjoyed the game. I kept telling them "but I quit." Lied several times. Bought the game several times after throwing the CD away or giving it away to my other friends. it wasn't until I gave my brother's copy back that I seriously grew over it. the turning point was when I started watching those Korean Starcraft videos on Youtube.com
I went back to playing afterwards, attempting to immitate some of the moves I saw in the videos, ...it was impossible for me. over the weeks I started realizing how much I was getting whooped on the Asia server and in Korean games on East server.
I was like... "how do they aim at spider mines with marines and not get blown into peices!?" it wasn't that though, because I remember how I used to go against the extreme players without my high APM and still managed to out strategize them with my lazy APM strings. I realized that I was growing up faster than I thought, and that video games weren't my thing anymore, since after only a few games I got incredibly bored, wins or losses. I don't know if I should pick up any more PC games. I went from console, to PC, back to console, back to PC... the last game I think I'm going to pick up is going to be Diner Dash, with the help of reminding me of the horrific accounts I played part in when I worked at restaurants.
