Games that push one emotion to much, Gears of War and Call of Duty was always so dour and angsty, then they try to make certain moments sad and emotionally heavy, but it doesn't work because they are just going from dour to slightly more dour.
In games that I personally found very emotional, games like Mass Effect, Assassin's Creed, Baldur's Gate, Red Dead Redemption, etc., there are moments of levity and peacefulness, even amidst all the anger and shooting and murder there are times where I can relax and have a quick laugh, so then when the shit goes down it makes it that much more serious and emotional because you're dropping from the highs to the lows, not from low to a bit lower.
