I had the same experience. I got badly into League of Legends in 2009 and don’t think I’d have weaned myself off of it as quickly if I didn’t buy a used MBP in 2010.
God, my roommate punched a hole in our wall when he lost once back in college. That’s the behavior of an addict, I assume. Then of course he paid our greedy landlord who demanded the whole apt be repainted.
I got into League of Legends pretty bad as well. Unfortunately for me, the MacBook Air I got in 2013 ran the game on low settings perfectly in OSX.
