Note: This is the standard computer AI from AoE II: The Conquerors expansion pack.
This release fixes the bug in Death Match games on Arena and Fortress maps that caused all civs besides Huns and Goths to only build towers on all difficulty settings besides easiest (until their stone eventually ran out, but by then it was always too late to start developing further). Also fixes the same AI bug in Wonder Kill games.
To install, simply unzip to the game's \ai folder, with sub-folders turned on, as all but two files go into a sub-folder named \STD AI DM FIX in order to keep the top-level \ai folder free from clutter.
In the Game Setup menu screen for Single Player Standard Game, drop down the list at "Other players" and select "STD AI DM FIX" instead of "Computer". This fix is for single-player games only and does not actually change any of the game's files.
An additional file titled "drs per xref for std ai.txt" is included in the download. This is a reference for where each of the included files is located in the gamedata_x1.drs file. This is a useful reference if you want to modify the Standard AI for a modpack.
Use these files at your own risk. They have not been produced by or endorsed by either MS or ES.
My personal thanks go to ES and MS for creating and publishing what has been a truly remarkable and enjoyable series of games.
