I find it amazing how people react negatively to having spent so much time in games such as WoW. If I take a step back and think of my times playing, my mind is instantly filled with nostalgic memories of having a ton of fun. This is coming from somebody who was deeply addicted and I have no regrets of playing as much as I did.
I started playing during the open beta back in 2003-2004 and I remember the first time I walked in front of the stormwind gates. Holy shit. If you've played it back then, you'll know that feeling. There might never be another game like it, so why not just be happy that you got to experience it? It's something nobody will ever get to experience again! I thoroughly enjoyed wasting my time in it.
