In my lower moments I don't look for games that will "make me happier" but instead games that will immerse me such that any low-feelings are masked or unnoticeable. Typically these are games that have several deep mechanics and let you makes interesting choices. Things like Civ, Crusader Kings or a good long JRPG with too many systems will pull me into a state where I'm not thinking about how bad I feel.
I actually find if I play games that are obviously "super happy" games that it jars too much with me internal state - I'm trying too hard.
