Uncharted 3 ideas.

[Carl]

I agree with Kantor - Holy Grail or China/Japan. Would also like to see him doing some more travelling, places like Egypt, India, England!

Few more things i would like...
Optional Co-op Campaign
More Sulley!
Environmental damage?
Travels to Greece, sees some cool Easter Egg regarding Kratos.

It's so hard to think of improvements to something so perfect...
