Now I have been reading through a lot of the product Phrogram (http://www.phrogram.com). It actually looks like it might be a good step to use after Alice (for my son's age) since it is still a beginner programming environment, it is still aimed at building simple games, but it takes the step of moving into a Code-Centric environment instead of the Object-Centered environment of Alice. It also says that it is a good predecessor to whichever "real" language he would learn - C#, VB, or Java.

Any comments on Phrogram?
