Every so often a game comes along that changes everything. Games like Doom, Super Mario Brothers and Half-Life aren't just incredible games in their own right - they helped shape the gaming industry as a whole. Halo: Combat Evolved is one such title. As a game, Halo evolved and refined the first person shooter, making it work on a console like never before. As a product, it helped define the first generation Xbox and help Microsoft become the juggernaut of today and, as a project, it lifted its creator, Bungie, into the history books as one of the most revered developers of all time.
In this new series of opinion pieces, some of Eurogamer's favourite writers reveal how they really feel about some of the world's most renowned, or most reviled, videogames.
In these heady, three-dimensional times where players are expected to move not just from left to right but also backwards and diagonally and sometimes in strange new directions they may not be comfortable with, level design takes on an all-new meaning. Levels now need to be both playgrounds and delicately constructed pathways. To stop their players wandering around aimlessly like children lost in a supermarket, developers must build their games so as to lead the player with an invisible hand.
Most big, modern games are, of necessity, a team effort - so much so that it's often hard to ascribe any particular part of the experience to one person. In the Halo series, for instance, all manner of people contributed to the games, and for the most part, you'd be hard pressed to pick out a great moment and say, "this person made this". It's a team effort. Everyone's fingers are in all sorts of pies, and every pie has all sorts of fingers in it.
