Well, I once worked at a games company that used Java. One of my colleagues coded up a small application that could run 'live' and provide detailed information about running code. The kind of stuff that I, as a Smalltalker new to the Java ecosystem, assumed was normal. This is when I realized that a proper Smalltalk running on the JVM would have revolutionized development in this company. Imagine developing your games in a 'live' environment, without all the lengthy recompiles and elusive errors. In other words, game development within the game itself. Much smoother, less stress, and a 'finger on the pulse' of running code.
