Something you've done in gaming that you were particularly satisfied with. Be it beating a game, or not dying in a halo FFA Slayer match, or whatever. What's the most satisfying thing you've done in your time gaming?

For me it really has to do with my multi-player experience with Team Fortress Classic. Just like college football has their top 25 the sites dedicated to the leagues and news regarding TFC had a couple of top 25 writers. On more than one occasion I was on the team that was #1. At one point one of the two teams I was part of (and was captain for) had a win streak over 50 matches. One of the teams was [NCA] and the other was .bP. That may give a few clues as to my username. More than the team success though I'm proud of the fact that nobody ever left either of the teams I was part of to join another team. A testament to the maturity of both teams and the fun we had.

I've been successful on iRacing and had lots of fun on Forza. Beat Gran Turismo 3 100%, but really none of that compares to the fun of the 4 or 5 years I spent playing TFC. How about you all? What's your favorite/most satisfying thing from gaming?
