LiveArea is the interface for games, and will let players launch the games, shop, or see featured news. Games were also shown to have Trophy support.
Yoshida went on to show Uncharted in action on stage. He made a point of the "micro analog stick," saying it delivers a "DualShock experience." The game lets you jump using either the X button or the touchscreen. When Drake is on a vine, players can physically rock the system to build momentum. When Drake climbs, players can use the rear touch panel to climb the vine with both hands. A stealth melee kill was shown, but the demonstration didn't show off detailed combat.
Yoshida also showed off a game called Little Deviants, which makes heavy use of the rear touch panel. It made a case for how the panel can be mapped directly to the screen, as Yoshida used his finger to create hills to move the characters, and tapped to make them jump.
One icon on the LiveArea interface is "Near," a location-based application. Near tracks where you've been and tells you the most popular games for the area. It even lets you buy the game directly if you'd like. Sony also plans to introduce "location-based gaming elements" and meet-ups.
Jun Takeuchi from Capcom showed Monster Hunter Portable 3rd running on the system, pointing to the possibility of backwards compatibility. He also showed off cutscenes from Lost Planet 2, being rendered in real-time on the NGP.
I might actually think about getting another portable game system again...!
