This is a tread to talk about games where AI / behaviour is a major gamepoint / the main focus of the game. Best example I can think of is Nero 2.0 which can be found here: http://nerogame.org/ In this game you have to "train" robots to survive in an area fight. You do that by building a training area and deciding what behaviour should get them points. For example they get points every time they hit a target (you can also give points for avoiding fire, going to a rally point, staying together, spreading out and some more). Now you spawn a number of robots which have random behaviour. The ones who hit the target get points (in our example). The ones with the least points get eliminated after a certain time period. The best ones go to the next round and form the "seeds" of a new generation of robots with mutated behaviour, which get´s tested again. After a while this can evolve to fairly complex thinking on the robots side. For example I once had a training area where I wanted to teach them how to take cover, so I created a turret which could fire at the spawn point and a wall slightly to the right and left of the spawn point and punished getting hit, so the robots just had to get the idea that they are safe behind the wall. After a few generations they took cover right after spawning and weren´t hit anymore. So I went to test it in actual combat. What I didn´t anticipate was that the robots didn´t learn that they were save behind walls, but that they were save by LOOKING at walls. In training they allways faced the turret and then went behind the walls with sidesteps, leading them to face the wall at the end. They acosiated that with savety. So evertime they were faced with enemy fire they jsut searched the nearest wall and stuck their face to it, becoming easy prey for the enemy. I felt sorry for the guys. Anyway, that´s the kind of game I am looking for. Other examples would be Black and White (the creature AI), Roboforge/Carnage Heart (you had to design robots and program their AI), Creatures. Special mention goes to 3D Virtual Creature Evolution, a programm which simulates the evolution of an entire body and it´s movment, which can lead to VERY interesting designs: http://en.wikipedia.org/wiki/3D_Virtual_Creature_Evolution Do you guys know any more games/programs like this?
