No WoW specifically, never played it, but Runescape had that GRIP on my psyche whenever I was younger. Late nights staying up to make sure I was still AFK skilling.

Now, it seems so dumb to spend so much money on a game that I basically played alone because CoD was the style at the time (and I guess still is), especially since it doesn't feel like I gained anything from it other than a love of the game and its style.

I had fun though, so I guess it wasn't all in vain?
