OK, I have been playing over 8 years, and I will never forget the moment in the game when I first went wow!!!
My first character was a NELF Hunter ( ok it seemed really cool back then to me, not so much now, LOL )...... and I don't remember exactly how I got to Menethil Harbor, but I had a buddy waiting there who escorted me to Ironforge so I wouldn't die. I recall being way too low to safely traverse the Wetlands.... As I walking along all I could think was "Damn this game is HUGE! It's been like 15 solid minutes of walking and I still am not at Ironforge." Not that I knew where IF was anyway, but it seemed like way too long of a walk. In fact, while walking, I almost decided to quit WoW because I didn't want to be walking all the time, LOL.
Anyway, those negative feelings all went away when I looked up the mountain and saw Ironforge for the very first time. I was absolutely in awe. And at that moment I was hooked on WoW...... 8+ years later, minus a month break here and there, and I am still playing, and a GM of a Horde and an Alliance guild on the same server, and the Horde guild was just started on April 3rd of this year.
When / what was your first WOW!!! moment in WoW?
