What are some of yours?
I remember when I first started, I was wandering around the Blood Elf starting area. It seems pretty nostalgic at times. That was April 2010 but I remember there was a heat wave or something that week which was also nostalgic.
I often feel really nostalgic about 2011, when I really got a good grip on the game. So much Cataclysm nostalgia, it reminds me of Spring weather as well because I always had my bedroom window open.
