13. Gears of War 3
Developed by Epic Games, Published by Microsoft
Gears of War 3 brings the trilogy to a fitting end, as it's the best game in the series by far. Right from the first mission, when the always-macho Marcus Fenix receives a message from someone he believed was long dead, it's clear that Epic learned a lot from Gears 2—unlike that game, Gears 3's pace never lets up. Stop-and-pop shooting has never been so much fun, and unlike in its two predecessors, you can actually find a multiplayer match.
