What's your biggest video game achievement? No, this doesn't mean when you won the watermelon seed spitting contest and Camp Morningwood, it means when you got 50 headshots in a game or something along those lines. Personally, it may seem a little stupid, but mine is getting 107% completion on Spyro 3. I loved that game SO much and got every single egg, gem, whatever, including the bonus world. It took a while, but I did it!
