I get nostalgic about a few things.
1. I get nostalgic about Morrowind, I have played it more than half my life. (Note my father bought it in 2002 and I was 6 at the time and now I'm 16) I can remember the first time I leveled up, I was to the west of Dagon Fel and I had just slaughtered some Mudcrabs, the game then said to me: "
You should rest and meditate on what you've learned." I remember an instance of being in Arilles Tradehouse and trying to read books to get level ups (I didn't know that only certain books were skill books

) and I accidentally picked up a piece of cloth, little to say the occupants all started to attack me until I was dead on the floor.
2. I get nostalgic about cartoons. I watched Ed, Edd, 'n' Eddy for most of my childhood and loved every minute of it. I remember once I watched an eight hour marathon of Ed, Edd, 'n' Eddy without doing anything else that day besides eat during the commercials and use the restroom. I still record some of the old shows so that I can watch them.
3. Runescape. Yeah yeah I know, Runescape is bad, it is just a grind, yada yada. Those opinions can't keep me from the nearly six years I played that MMO from 2006-2011. I remember facing Nomad (A extremely tough boss) and finally beating him. It was such an accomplishment I still remember the day I did it. May 30th 2010. I remember spending nearly 46 hours playing during a weekend, man that hurt the following Monday.

I remember getting all the quests complete and finally claiming the Quest Point Cape, all my friends were there, it was quite a good day.
