What was your favourite moment in gaming?

I think my favourite moment was the first time I ever played online on my xbox 360, it was also the first time I'd ever played online on a console.
Single player wise, I think completing Baldur's Gate felt very satisfying and compelled me to move on to the sequel.

Probably camping out for a Wii on launch day. Anybody who has ever done this knows the feeling it evokes.

Probably WoW when I played/communicated with dozens of people at once, some of which I knew personally. I thought to myself "this is it, every game will have communication to this degree someday" Also, Rugrats Search for Reptar. First game I've beaten. 

look at my icon, best moment ever
