My #26 is GoldenEye 007 (1997).
Before the release of GoldenEye 007, most first-person shooters were corridor shooters that had one simple philosophy: shoot first, ask questions later. These shooters, mostly clones of Doom, asked their owners to shoot everything that moved, and little else. GoldenEye changed the prevailing paradigm by introducing mission objectives that demanded a combination of firepower and brainpower. GoldenEye is perhaps most famous for its legendary multiplayer modes, which allow four friends (or enemies) to shoot at each other in a number of environments with a variety of weapons. The legacy of GoldenEye is most evident when this fact is considered: console games released post-GoldenEye which did not feature a multiplayer mode were considered somehow incomplete.
