What's your greatest video gaming acomplishment?

So I just beat the hardest boss fight in the entire Kingdom Hearts series and I wanted to know what do you think your greatest accomplishment in video games is?

Facing a Unicom in the same tank, and beating them one on one.
If you don't know, and I normally wouldn't... "Unicom" refers to someone within the top 0.01% in World of Tanks, also considered "pro" (and some of them actually are pros). For comparison, I'm in the top 18.00%, or what is considered, "good".

Actually, one of the times I did that, the other driver saluted me... that is actually probably more of an achievement.

Not destroying my TV and NES after falling in the same pit three times in a row in SMB1 8-1, losing all my lives and having to start over.

I'm TERRIBLE at video games.

I suppose a more serious answer would be logging over 320 hours into Skyrim. But that just takes time, not skill.

I guess on a pure skill level I'd say sticking with Far Cry 2 until finally beating it on Easy.

And yes, that truly felt like a big accomplishment in gaming for me.
