interesting point. It was not conceived as headstart, but it is sold as headstart. I want it as a real game, and i want it as an efficient learning tool. I want it for discovery and shared learning moment, and i want it for avoiding math challenges later. I want it for pleasure and i want it to teach very difficult stuff quickly. Seems like many contradictions here. arghh u revealed that i m human i guess : ), with incompatible goals and complex realities. At the same time, this complexity and contradiction makes it a very interesting challenge : )
