The first image, of a space-marine-type figure fighting green aliens, is when Wreck-It Ralph visits "Hero's Duty," a "Call of Duty"/"Halo"-style game. This is where he meets Jane Lynch's character, Sergeant Calhoun, who serves as a friend and ally to Ralph. The image is dynamic and totally captures the spirit of those games (overwhelming chaos) incredibly well.
Next, the second image is more sorrowful -- it's Ralph looking at an apartment building with some decidedly "Donkey Kong"-style fire escape ladders. We could see this image coming from the first part of the movie, with Ralph deciding that he's going to be something more than a one-note videogame villain.
And the last image looks like it's from a "Mario Kart"-type game called "Sugar Rush," which is where he encounters Vanellope von Schweetz (voiced by Sarah Silverman). Again: this looks spot on, with the different lands and the cutesy, cartoony art style. This will also be a key set in the movie, but we're reluctant to say why.
We are certainly excited about "Wreck-It Ralph." It hits theaters on November 2, 2012.
