I really don't think there needs to be any more Uncharted. Too often now are companies focused on producing more and more from an IP until returns diminish and not when it is a suitable time to end. Uncharted 4 is one of the most fitting endings to a series I've ever played and I would not want to see any more from that world unless there is a spectacularly compelling reason to go back, like an Uncharted Kart racer. Where is Unkarted?
