i know, nobody is listening to me, but i stay by my idea!

Do a Zak Mackracken Remake with the engine and the Charackters of Uncharted!

King Solomon's mines?

Oak Island.

And by clues you mean random symbols that are on the wall, and, oh wait, all the answers to the puzzles are in your notebook.

That is one of my biggest complaints about the previous games. I'd like it if the puzzles are not so childishly designed and had some depth, and required some thinking to solve. They don't need to be hard, but they pretty much do all the thinking for you. They're just a complete waste of time, and serve only the purpose to break up the action and cinematics a little bit more.

Also, more 'realism'. By this I mean don't have Drake get shot, climb up a train a car hanging over the edge of a cliff, while giant rocks rain down and he miraculously doesn't fall, twice. That ruined the immersion for me in U2 at least, U1 was a much better game in those regards so I liked it much more.

This is the trap of a modern setting game. At least for me, I tend to judge them based on laws of physics and 'laws' of reality in our own world, and when things don't line up, it bothers me. U1 was great for that, no problems at all. U2 was atrocious. And I'm not even talking about the whole getting shot and healing thing, or shooting through 100s of enemies through the course of the game. I know most people don't care about this kind of thing, but it's very important to me.

I'd like to see Naughty Dog try and break the mold, and do what Bioware did where they essentially re-worked their formula for ME2, but not in a way to lose the general "feel" in ME1. U1 and U2 are pretty much the same game, just different stories (great stories though). If U3 is the same thing again, I will probably avoid U4+ (if it gets that far). In otherwords, spend less time on graphics + cinematics (not usually too important to me) and more time on deeper gameplay.

Oh, and fix the jumping. I can't even count how many times Drake jumped on air (overstepped the ledge and still managed to jump).

As for the actual story, I'm pretty sure whatever they come up with will be as awesome and epic as the other 2 games, I trust them for that. But, to me, the gameplay is seriously flawed and needs some more attention.

I dont think people would like mermen as enemies.

Not Atlantis just yet.

I say the Holy Grail.

more rpg like customisation, retain awesome gameplay

In search of the treasures stolen by Nazis like Amber room, gold from Greece (recently mentioned by Greek politicians LOL) etc

Instanbul would be a great destination,but Drake already visited it in Uncharted 2.

Coop? LOL.
