7. Voice recognition
We're expecting AI to come on in leaps and bounds by the time we're playing GTA 5 on our PS4s, so although this one's quite out there we'd love it to become a reality. We want to be able to speak as the lead character. If you wander up to a character and speak to him using your own voice, the game is advanced enough to understand and generate an appropriate response. We're not talking about pre-set conversations, but proper responses that add life to everyone you speak to.
