Having played the 2nd Uncharted on the PS3, I was worried that coming to the Vita to play an Uncharted game might present an extremely thinned out version of its bigger brother, the PS3. Thankfully this is nowhere near the case, as the Vita manages to maintain a high standard of polish and presentation that emulates the console versions near perfectly, graphics and all. Now I'm in no way suggesting that a handheld game has managed to look exactly alike as the PS3 version of the game, and it's noticeable in places that the levels have been significantly scaled down to accommodate for the lack of power compared to the PS3 (trees in background being 2d billboards, mountains being elaborate cut-outs too etc.).
However, even though the game has been shrunk inwards ever so slightly in scope, things such as screen-space-ambient-occlusion and dynamic ray traced shadows are still present. Sony realised the importance that Uncharted: GA make it to the Vita's launch lineup, as it not only demonstrates the power of the system, but also the potential.

Also, most of the touch stuff was optional too, so you play how you want to play.
The only thing I found that got tiring was the rubbing, which was not optional.
Still loved it. Might replay it sometime soon. It did show off the vitas capabilities nicely.
