Java is also usable language for entertainment even to implement a performance demanding 3D engine. I have been thinking about kicking my own jMonkey Engine based hobby project forward but after spending eight hours working with Java in business project I don't really have motivation to continue development at home. Maybe I should have a holiday to code at home :-)
