When I tried intense x it wasn't really that great because you couldn't do anything but have some ai enemies shoot at you. If you wanted to add any of your own functionality you would need to disable the intense x. It was too laborious to use the intense x functions on their own.

It would be better if you had created a library of modular functions which could be incorporated into an existing code base rather than force any user to understand the whole code system before they can do anything original.

As it was when I got it, intense ai was just like a FPS creator clone, which is extremely limiting and boring.

I have been looking at mercuryus pathfinding code and it looks very simple and efficient, the pedestrian avoidance looks just as good as yours. Why it looks better is perhaps because it will actually be usable.
