Death Race (Unlicensed)

Death Race is a vehicular combat video game developed by American Game Cartridges for the Nintendo Entertainment System (NES), and published in 1990. It is a remake of a 1976 video game of the same name.
Nintendo Player described Death Race as the "spiritual predecessor" of the Grand Theft Auto game series developed by DMA Design, which applies major gameplay elements from Death Race.

This longplay covers all difficulty modes (including an extra mode after World Class which is the hardest one). If you start from Rookie difficulty, you'll not only get a huge amount of money, the best upgrades you do to the car will also be kept after finishing any mode.
