Best: Halo 3

While the Xbox 360’s launch titles weren’t great (more on that in a moment) it would eventually make up for those games with some generation-defining bangers, like Bungie’s 2007 classic, Halo 3. It’s hard to explain just how big Halo 3 was in 2007. It was the game everyone I knew was playing. It was all over the news.
A few months later, Call of Duty 4: Modern Warfare would arrive and begin chipping away at Halo’s dominance on the console, but for a few years there before CoD took over, Halo 3 was the biggest and coolest FPS on the planet.
