Halo: Combat Evolved
There are only so many truly revolutionary titles in the history of video games. The Legend of Zelda, Super Mario 64, and Wii Sports come to mind. Then there's Halo: Combat Evolved. What did it achieve? Well, by providing the nascent Xbox with a "killer app," it secured Microsoft's spot in the gaming world. It also introduced features, control schemes, and themes that have, for better or for worse, infiltrated almost every mainstream first-person shooter since. And, lastly, it shifted first-person shooters away from computers and onto home consoles. So it's a hugely influential title, but it's also an amazingly great game, with superior graphics, a standout soundtrack, a well-written story, outstanding level design, and perfect gameplay.
