Alright. This topic has gotten a good amount of replies, so I'll put mine up.
My very first console was the Sega Dreamcast. So as you can imagine, my first console was very short lived. For quite a few months, all I had was a demo disc on it. Me and my brother tried game tirelessly on it. It had quite a few forgettable titles. My brother's favorite was Pro Bass Fishing. But my favorite was just so amazing, I wanted more of it. Sonic Adventure. Christmas was coming up soon, and I asked non-stop all over for Sonic Adventure. And when Christmas came, I finally got it. I didn't have a memory card, so I had to play Sonic Adventure immensely to get anywhere. Everday was a new start, and I drilled into the game again and again. After the intense hours put into it, I knew that Sonic was going to be my first choice of gaming.
