More Balanced AI in Tiberium Dawn

Balances the money per harvester for the AI to match the player, may cause issues in some campaign maps (unconfirmed).

Normally, human players get 700 credits per harvester but the AI in Tiberium Dawn campaign gets 17,700 credits and 924 in multiplayer/skirmish.

This mod changes it so the AI always gets the same credits per harvester as humans, 700.

This does not change any other aspect of the AI. Depending on difficulty AI still get more money for selling structures, more damage, etc.
