The Uncanny Vally in Mass Effect 2 and Half Life 2. The human characters featured in these games are incredible graphically detailed and they are modeled after real people.

Even though the details from the game characters are quite similar to their real world counterparts they fall into the Uncanny Vally as being robot like with human features. We humans know how every movement looks in facial expressions and can tell whats not right and this uncanny look in game characters disturbs us. Even though these characters are very detailed in trying to replicate human emotions and expression, we are disturbed by this as they are life like, but are still showing some robotic movements to them.
