Dragon Age: Origins, got my mods and can skip that horrid Fade part of The Broken Circle.
Go medic, No heavies. Go heavy, no medics. Go anything else, everyone follows you around screaming "Medic!"
Go Medic and people from across the map will scream medic, expecting you to get your ass there to heal them up.
And one of my favorites: Heal a guy and he believes himself to be immortal, running in alone expecting you to still heal him as you both go and die.
