Uncharted: Drake's Fortune is an incredible game, there's absolutely no way around that.  However, the number one complaint levied against the game was that it was too short, and there wasn't enough of a reason to keep coming back.

Naughty Dog looks to be addressing this issue in the games upcoming sequel, Among Thieves.  When asked about the game's length in a recent interview, Uncharted co-designer Richard Lemarchand replied that Naughty Dog is implementing a new feature in the franchise that will "increase replayability" and "extend the gameplay experience".  He was tight lipped as to what that feature may be, but teased it would be revealed soon.  Do we smell multiplayer?

Uncharted 2: Among Thieves is an action adventure game developed by Naughty Dog.  The highly anticipated title is due out later in 2009, exclusively for the PS3.
