I think the path finding was one of the crucial elements that lead to porting AoE1 to the AoE2 engine (which was released just this month DLC Return of Rome). So there are some cases when it produces weird behavior, but in general I like it.

Nevertheless, I admire 0AD especially for the consistent progress and commitment to the game. It has been a while since I played it the last time. Might be a good occasion to start it again!
