17. Gears of War 3 (2011)
Platform: Xbox 360
Take a nearly universally praised series, polish up the rough edges, and bookend the spanning narrative with a whole new suite of multi-player functions. That's what Epic did, and harvested nearly endless positive reviews for Gears of War 3. Often cited as the best game of the series, the title is still played competitively to this day. And, yes, we know that technically it's a third-person shooter, but that's a pretty short list, so it makes its way into FPS territory.
