This is one of those AIs that can't really be improved upon. Removing Food According To Population is an invaluable aid to designers of B&D scenarios that deducts food per population. To do a similar "food eating" system in the past, designers would need to set masses of triggers detecting all possible populations, (5, 10, 15, etc.) By comparison, this AI is a breeze to use, as it is mostly automated and you can add it to a scenario with just a few triggers.
Hopefully this AI will provoke some more interested in the somewhat ostracised B&D genre. In even the best B&D scenarios, the most challenging part is normally the beginning, before the player has developed a strong economy. To quote Puzzleman: "Most B&D scenarios require the player to fend off an initial attack, become impregnable and then sally forth to conquer. The scenario is actually won in the first 15 minutes and then it takes two more hours to prove it (kinda like Monopoly)." This AI makes it all to easy for the player to lose without getting attacked at all, and I think will improve the lopsided balance of many B&D scenarios.
This AI is easily customizable. The author provides very good written documentation explaining how the script works and how to modify it to suit the designer's needs. It requires you to devote a player to the Population Counter AI, but the author thoughtfully included Zanzard Lothar's Immobile Units AI so it needn't be a dummy player. You can just rename the file, edit out the "Your people are eating food now" line, and the AI can be used just like a normal Immobile Units player.
Recommended for everyone who has the slightest interest in designing B&D scenarios.
