I have loved the civilization series for the majority of my life, and I think this mod in particular is amazing. However, I can't help but get frustrated with both Civ IV vanilla and to variable degrees it's modifications because of what I feel is underdeveloped AI. I am here to talk about it, and I chose this forum because I think Fall from Heaven II is brilliant in both concept and implementation and suffers only from this basic weakness of CIV IV.
That being said, I get frustrated most specifically because I feel that the advantages given to the AI at higher difficulty levels to make the game challenging is an inadequate substitution from a truly skilled AI. I can only imagine how difficult it must be to design a competent, non-cheating AI in a game as complex as CIV IV. However, I have seen at least one game (Galactic Civilizations) that seemed to succeed quite admirably in this regard. To a certain degree this has always been a problem of the civilization series, but it seems even worse to me in CIV IV.
