I can relate. I played
Starcraft:Brood War from 1998-2002
Warcraft 3:Frozen Throne from 2002-2010
The competing was the essence for me, I did play other games at LANs or some casual games at console but for the absolute most part I played to win in those games.. at that point in my life getting really really good at a specific game was definitely more rewarding than beating a dozen or so games a year like I do now.
