Three: Mass Effect 3
To get it out of the way—yes, I hated the ending. But I hated the ending because the previous 95% of the game had been such a stellar ending to the stories of Commander Shepard, Garrus, Tali, Liara, and all the rest. For example, the high point of the game comes during its Tuchanka mission, where the emotional stakes of the Krogan genophage come together in a sequence that’s as well-done and nearly as emotional as anything from The Walking Dead. But unlike that game, Mass Effect III has great gameplay to back up the story presentation—immediately before making your final plot decisions on Tuchanka, the game has an amazingly intense battle with four of the giant Brutes attacking you at once (a battle commonly matched at higher levels of the multiplayer as well). Intensity of mechanics combine with intensity of storytelling for Mass Effect at its best, and that happens many times in Mass Effect III.
