Bit of a serious post but don't run away !!!!!!!! I need you 
I'm writing a dissertation for my final year at uni about the impact of emotion in video games. So i would very much like to know of your gaming experiences.
I'm specifically looking for which elements of a game/s you enjoyed the most. Was it the story, a character, the multiplayer aspect or a specific game mechanic that you felt drew you into the game?
What made you happy or sad, bored or invigorated?
EG: The first game i ever felt I'd really really enjoyed was Half Life 1, the story really pulled me in and left me wanting to know more.
Whereas the most fun I've had in a game was in Lineage 2, due to multiplayer interaction.
So any old MMO you miss and want to see back because nothing else has the same feel?
Spent endless hours playing a game with your friends and not found anything else like it since?
Anything, good experience or bad, tell me about it!
As much or as little info as you care to write, it's all useful to me.
