It usually depends on how much I like the gameplay.
With the Bethesda sandboxes (with the slight exception of Oblivion) I usually actually go for the hardest difficulty because I like the gameplay and how the Bethesda Fallouts and Skyrim do alot to make me feel like a badass.
with the Dragon Age games, I go with the Casual difficulty, because I'm mostly in it for the role-play experience, but partly because in Dragon Age Origins, with the non-mage classes I play as, my Grey Warden seems more interested in running around like an idiot then attacking one bad guy even when it's the only bad guy in the room.
With Mass Effect, the first I keep on Casual, while the other 2 I play on Normal or Harder, because combat to me in those later games is more balanced, intense, and overall enjoyable.
