Started with Morrowind (it was one of those games I bought on release day then swore at my PC for a while and finally got to play it a few months later after a major hardware upgrade!!!) Then went through the exact same process when Oblivion was released :cryvaultboy:
I'd been regularly googling "TES V" for ages hoping for an announcement, hanging around the forum here on and off for any whiff of real news. I became utterly convinced that there would be an announcement on Spike TV VGAs towards the end of last year (despite a lot of people here saying that there was no way Beth would do a big announcement there, I had a gut feeling about it for some reason) - so convinced that I found a live stream of the TV channel online and waited up to the early hours of the morning to watch it.
Then Todd Howard was announced and came on stage and there were robed figures and stuff and then the first second of the trailer and I gripped my husband's arm and spent the next few minutes jumping up and down and *ahem* sort of crying a bit
(while my husband no doubt wondered whether he should phone for a padded ambulance) and I was so excited I missed most of the teaser trailer! Then I came here and posted some excited comment along the lines of "yay" but in upper case with loads of exclamation marks after it, you know the sort of thing (almost acceptable coming from a 6 year old on their birthday, but not very becoming of a middle aged woman). And I never did say "I told you so" to those who poo-poohed the idea of a VGA announcement - it didn't take me too long to regain my composure
