Well considering it is probably a copy of someone elses who spent weeks figuring out the math required to do path finding while working on MSDOS or something. I kind of agree.

But then you see it also includes developer support and such so it all makes sense.

However this does lead to an interesting concern, what's the difference? I don't seem to see anywhere were it says you can't use the free version for commercial? Or what you get for free and what costs $60?
