I played in beta then a few months after it came out. I stopped because I moved out for school and I didn't bring a computer that could run SC2. Since I couldn't play I lost interest for the most part. I'd follow leagues every once in a while for a bit but then something else would catch my interest. I'd sometimes also play when I visited my family, but for the most part I've been very inactive on Battle.net.
This weekend I saw the NASL finals live. I followed Scarlett as + Show Spoiler +
she teared the living shit out of the CWS
We'll see how long this inspiration lasts but so far it's been a hell of a lot of fun getting back into laddering mode
