The one game that "sold" me on a 2nd hand OG Xbox was Toejam & Earl III: Mission to Earth. Nice to see what happened to the series after the Genesis games. I wish you could skip the choir scenes though. I bought my system bundle way back then from half.com when they still sold game systems. This was also just as the old Game Crazy chain was clearancing out the system's games.
I have no idea what to do once the ancient hard disk crashes, I am kind of worried to use it.
