I've still got one, but I gave in and traded away my best games when Amazon were offering ridiculous prices. I got more money back from most of the games than I originally paid for them. I spent literally thousands of hours playing the original Phantasy Star Online. Happy memories.
It's my all-time favourite game console. It's a shame to think that it was the straw that finally broke Sega's back and sent them running from the hardware manufacture side of the gaming industry.
