I will give a brief overview about current research on computational and artificial intelligence in games in my group at the IT University of Copenhagen. There is a wide assortment of interesting CI/AI challenges motivated by modern computer games. Our projects include predicting player behaviour and player emotions, automatically constructing levels, environments, items and whole games, generating human-like playing styles, and learning to play various games well. I will also ask what it would mean for the game to play the player, and whether an AI needs to have fun.
