The question of ethics in video games is one that we think has been resolved by companies such as Bioware and their 'morality engines' in game. However, this is only an illusion.
The approach to Ethics in the stories of videogames is, also, positively Kantian; it drops all context. Game companies claim to have successfully addressed the issue with their 'wheel of morality' system-- in dialog trees, you can usually choose between two options at important junctures. Each option has a different moral posture. In this, Bioware implies, we have finally managed to include ethical dimensions. Except that this isn't quite so.
