Hmm, probably completing 'The Warrior's' on PS2 several years ago. It doesn't sound like much, but before I was 10, I had never the motivation to complete a game all the way through. Not even Crash Bandicoot. So when I completed that game it was a big accomplishment for me.
Next, I'm going to try and reach the second save point in Silent Hill 2.
