No, Halo I and 2 sold well because they had great stories in their first player modes for console shooters. Also, they had features not seen before in console shooters like the ability to switch from FPS modes to driving vehicles like the Warthog, tank, ghost and flying banshees. Also, they had the best graphics of any console games of their time (The Conduit doesn't really look as good now), awesome music, and strong muliplayer aspects. I haven't played Halo 3, so I can't tell you if it matches up with the first two or not.
Uncharted is popular because it has one of the best stories seen in an adventure genre item even in movies (it is better than the Crystal Skull story and characterwise for sure), great music, more gameplay elements than Gears and definitely more than flick your wrist this way to hit the ball or swivel your waist and lose some weight.
Well have fun playing the slew of second rate survival horror and rpg games that Nintendo is bringing to the market to try to appease core fans until the release of the next Zelda and Mario in 2010 and in the Wii games that you play for a couple of hours during a sixth month period after their novelty wears off.
Heavens to Murgatoids.
