Most rewarding, satisfying gaming accomplishment?

Halo 2 online. Capture the flag in Coagulation, I do believe, whichever one used to be Blood Gulch.

Me and my friend warthog to the other base, I nip in to grab the flag. About to drive off, he gets shot. I then proceed to run the flag back to our base. To this day I have no idea how I managed it.

Trialling for a very skilled clan on CS 1.6, and having a freakish day where I absolutely raped the clan leader and every other clan member. And I'm only an intermediate level player, and these guys were advanced. I was in some sort of wierd zone of concentration that day.

That, and beating my younger brother at Mortal Kombat for the first time. Sad I know, but he does play it way more than me.

They day Blizzard had buffed Ret Pallys in WoW was a great one. First time seeing my name hit the top of the damage lists after boss fights was just an amazing feeling considering the other people in the raid had gear way above mine.

That and getting a 44 kill streak on the Sniper in TF2. Best Two Fort ever.

The first time I passed 'Green Grass and High Tides' on hard drums was my greatest Rock Band accomplishment, it was the fith-ish time I tried it and I was just elated.

This, except on expert guitar. I tried that second solo at least 50 times before I finally got it.

Not finishing a Metal Gear game, but rather sitting down and interpreting the plot, picking up all the hidden themes and actions that were only implied but require inference.
