Penny Racers was the jam, way back in the day. It was our family game, but unfortunately I played too much, and no-one could keep up.
Circuit Breakers is a really good Micro Machines clone. I still take it with me when the old ps-systems get carried around.
Biofreaks and WU-TANG:enter the pain are so much fun. Stupid gory party fighters with more jank than a dump site, but I don't care.
