Yeah i started out with Xbox Live when i was high school too. I was at my peak in gaming when it came to high school. Luckily it did not affect my schoolwork. lolI believe my xbox live journey started when I was a freshman in high school (6 years ago) and it all started because of my best friend from Singapore.
I've had my xbox 360 for years, but when I was in the Philippines (initially XBL wasn't fully supported) my best friend brought his copy of Halo and he gave me his trial code that came with it. Awesome and needlessly to say we gamed on the social slayer playlist all night for as much as we could.
I don't regret it!
