have their write up here too in case it gets pulled,
Uncharted has left the biggest impression on me. At first, the game reminds Tomb Raider a lot of running, finding ways out, mount climbing, jumping and puzzles. The game has a nice combat gameplay and you never feel a need for another kind of controller, a keyboard or a mouse. For example, your character engages a squad of hostiles and takes cover so when you return fire the pointer is always near one of the hostiles the game assists you in targeting greatly simplifying the process.
At some points you can use the touchscreen and the G-sensor in the game: when the character needs to over some logs instead of using the arrows you can scroll through the logs on the screen. Another example: when jumping over pits you can tilt the console a bit while pressing forward and jump to increase the jumping range of your character. The game uses your natural moves just remember how often you shake the gamepad trying to push your character.
The graphics is excellent while I was playing I wasn't paying attention to details like shadows, dynamic lighting, wind in leaves of trees and bushes or models of NPCs. What is important is that all these details actually create a world and you don't notice any flaws that would put you out of picture. Uncharted is a very cinematic game there are a lot of script scenes and spectacular camerawork, close-ups and panoramas and it all looks very nice or at least it does in the demo I have tried.
One of the interesting I games I have played but failed to understand is Little Deviants. You play for um a ball that rolls over countryside without any route or goal while knocking over obstacles and opponents. The absence of any goal is made up by nice graphics and ability to change the landscape. If you press the touchpad on the back the landscape changes getting rougher. This is another example of how the multitouch works here.
I have also tried Reality Fighters a funny fighting: you can customize your fighter make a brutal fighter or a manager in suit. You can use pictures as the background for arenas and use photos of people to create opponents.
WipEout 2048 an arcade racing with very vivid graphics and a complicated (for me) control system you not only need to press the right buttons but also tilt and turn the console to get into turns.
