There are some bad racing games for Java, titles that offer no feedback and no real purpose. Because of this, even a mediocre game like Police Car Speed Race can look good.
All you have to do is avoid cars as you race down a highway in a police car collecting coins on the way. You can use coins to unlock more vehicles but this is made tricky due to game's the odd perspective.
PCSR isn't perfect, but it at least offers good controls, decent graphics, and collectibles to keep you high-score chasing.
