If the reply was for me, check with whom I agree and you''ll see that I don''t find AI easy, just some easier than other.
AI are hard to programm efficiently and nicely, with good functionnalities.

I totally agree, to get good AI running smoothly takes a lot of time and design. None of it is easy and the functionality of a single concept like pathfinding can require quite different implementation between two genre''s of games.

I''m just glad that developers and publishers are appreciating the need for better AI in games.
