Happiest was finding Paarthurnax and listening to that wonderful Dragon tongue.

Saddest time, hmm... when I realised I couldn't marry Lisette. Actually, it was more of a "Oh Bo**ocks" moment.

- saddest moment. happiest moment - was discovering all the new holds and cities.

Jo'Nyan was happiest to set up camp with her beast brethren, Whiterun looked so welcoming...

This one awoke to an empty pasture, whilst saddening, comforting to know Moonsugar was left for 'Nyan!

Happy: seeing birds. I'm not kidding.

Sad: the ONE TIME I figured I'd bother with crafting, Thugs come to slice me in half. So much for crafting

[censored] i wish i was english so i could say that and be a bloke

Some sad moments:

The last assassination in the DB quest-line. I could barley do it, and afterwards i was like
I felt so bad i even regretted looting him/her.

Finding blackreach. To think that a entire race was trapped and deformed there is just... Created a great deal of anger towards the dwewer too.

The fate of a certain person whos name begins on A. Despite the persons previous betrayal i could not help but to feel very sad

Happy moment:

Finding a dragonplate shield in a chest at level 33 . Its a shame my char was a mage, but it sure looks good on my wall in Hjerim.

Also the anticipation just before i got to play the game for the first time!

This topic should probably be in spoilers.

Happiest: Not sure about genuine happiness, but some of the battles I'd been through were very fulfilling, defeating Olaf One-Eye and other powerful foes.

Saddest: Probably the Morthal quest, finding the little girl was quite sad for me, really moved me to complete that quest.

Happiest: snapping the disc in half

Saddest: My brother bought a new copy

My doggie got killed.
