Immersion is how well they integrate the gameplay with the visual. Since that is our connection to the game, what our motor skills do and what we see. Running and hitting an invisible wall takes you out of the game, listening to boring dialogue and extended cut scenes takes you out of the game.

Good examples of immersion: Gears of War, CoD4, Zelda games, Mario Galaxy, Grand Theft Auto, Shadow Complex. Games that really use unique ways to keep you IN the game.

Bad examples of immersion: Metal Gear Solid, most Spider-Man games, Tactics games (I love 'em but they stink at it), Assassin's Creed
