Yep. Sold my 5k acc after wasting nearly 3.5k hours on it. My grades (uni student) and social life has suffered a lot playing this game so much. I always try to quit but then will reinstall a few days later. If you are a competitive guy, you will get addicted to this game easily. I started off as a noob at 2.2k mmr and climbed to 5k solo q only in about 3 years. But then you realise that most people playing this game at high MMR are already super addicted and can't stop even if they wanted to, and you are becoming like them. It's no different from drug/alcohol addiction (only that it doesn't affect your physical health much). Sadly most of us players don't even have a job/good education and are wasting our youth on this game.

It's important to recognise when you are addicted and stop... I wish I never started playing Dota 2 when my friends introduced the game to me. I went from being a straight A student to barely being able to pass uni exams.
