The Protectors of Etheria is a stand-alone mod of the game Warlords Battlecry 3 (i.e. it can be run without having the original game installed - 100% free full game). It is an improved RTS/RPG game with new campaigns, quests, terrain, units, items, heroes, modding features and more. Beta versions available for download!
In 0.9, the AI will prioritise attacking players that are on the verge of being defeated (or are doing exceptionally bad) so they can remove them from the game easily, take their mines and stop them from trying to make a comeback.
This does mean entire AI teams can end up focusing on a singe player once it spots an enemy that has started to falter. In this game, for example, the poor player in the bottom left corner of the map eventually got swamped by all 3 of the sides from the top team and then things just snowballed out of control for that losing team.
Now that's diabolical. And fantastic :)
Just for clarification - the AI will treat all players the same when it comes to evaluation who's down and needs to be kicked out. So it will indeed do this to other AI players as well as human players.
I approve this message. Nice one, very necessary for actual balancing.
