That's so weird because I too dropped Sonic's Adventure for the Dreamcast for years before I went back and beat it. I got Sonic and the Dreamcast when it first came out when I was about 9 years old and at first I didn't have a memory card because I'd never needed one before. Then when I was about 15 or 16, one of my friends mentioned the game and I had to go back and finish it after all those years. I still had Sonic and Big left to 100%. I remember playing against the last Robotnik and using about 20 lives. As fun as it was to beat each campaign individually, nothing topped finally beating all 6 and then beating Supersonic. It was the most satisfying feeling I've ever gotten from gaming.

I spent this summer going back and beating xbox games I hadn't beaten, then at the end of the summer I sold a large number of my games. I figured I wouldn't spend as much time at college playing games and I was right. I remember going back and beating games like Jade Empire and it always felt better to finaly beat a game I'd put down. I know I still have games like Ninja Gaiden and Prince of Persia 2 that I never beat, and I'm sure someday I'll go back and beat those games as well.
