What are the games that changed the world (of gaming)? I'm talking about games that did for the games industry what the Beatles did for music and The Matrix did for films. What are the most important games ever made without which we wouldn't have some of todays offerings? Here's a few examples. Wolfenstein 3D (1992) The undisputed grand daddy of all first person shooters. If this game had not been made we wouldn't have had Doom and it's reasonable to assume we might not have had things like Quake, Half-Life, Halo, Crysis and Call of Duty. Probably the most important game of them all. Oh, and it had Hitler dual wielding mini-guns! Metal Gear Solid (1998) Although Tenchu was really the first modern "stealth 'em up" it was Metal Gear Solid that really brought it to the masses. Everything about this game was a level of epic not seen before in a video game. The story, the action, the music, everything was designed to play a role. It was also one of the first games to really interact with the player. Examples of this are Meryl's codec frequency (which was required to continue the game) actually being written on the back of the game's box, and Psycho Mantis commenting on save files on the memory card or moving the controller with his mind, freaky. Hideo Kojima took game direction several notches higher than it had ever been, and the trend continued not only with subsequent Metal Gear Solid games but games in general. Gran Turismo (1997) The name says it all. Gran Turismo, The Real Driving Simulator. In the mid nineties racing games were usually confined to a handful of cars and even less tracks to race on, until 1997 that is when Gran Turismo burst onto the scene. Boasting over a hundred real world cars ranging from Nissan to Aston Martin and over a dozen tracks plus the option to earn money and tune your cars making them faster racing machines, was more than anyone could have hoped for. The game featured a level of realism not only in the game physics but also the graphics that was hitherto unseen in a racing game. Gran Turismo literally set the standard for racing games and the series continues to do so 14 years later.
