Honestly?

Zombies

Not joking, I think an adventure dealing with zombies would be sweet. Ok I haven't played the first one so I have no idea if it would even fit but you asked what *I* wanted =P

Truth be told I'll probably never play the game, so hopefully they don't listen to me =P

Hmm, I'd want a longer game and more variety. The game simply had too much shooting and too few platforming.

I didn't think the zombie thing was all that bad, unfortunately I was spoiled before I got there :(

I want more grenades!

Would be also cool if there were more hand fights, like one entire level in which enemies and Nathan doesn't have guns.

Sqrl, It's one of my favorite PS3 games... But I never beat it, because I got fed up with my PS3 and it joined my 360 at gamestop. I am up for multiplayer and varied environments. Like resistance, don't judge it by the crappy demo (why do they release crappy demos?).

I didn't like the plot twist at the end, so without spoilers, don't do anything like that.

I also thought the humans looked a little to plastic. Fix that.

I remember an interview when the game came out, and in that interview the dev's said they used only 30% of the CELL. They said they way they develop, is it figure out everything that's going into the game before they develop, and once it's all done, scale back what won't fit (CPU cycle wise). They said to there surprise, it all fit with only 30% utilization.

I am not sure if that's PR BS or the truth. If it's the truth, expect a lot more from Uncharted 2.

it alreay has zombies in uncharted 1 and it works beautifully with the story twist.

Less cliche riddened storyline, better enemy AI (and better enemies instead of the racial stereotypes that were in uncharted), probably larger combat areas and definitely a longer experience would be great, seeing as how it lacked online multiplayer and all.

Also, online (co-op or vs) would be a welcome addition.

NO ZOMBIES!!!!

seriously, wtf, they just kinda ruined everything, I had to like CQC them all with a shotgun to the face

The first was great but little short so they should make it longer.

better graphx, longer story and possibly more varied levels
