Yes, Terrorist hunt in Rainbow Six Vegas (the first one, aka the superior one) since you can die so easily, even the regenerating health is of little help. The sheer fact that I could die any second really gets to me, and funny thing is it isn't frustrating when I get killed by the last guy, its only a relief... at least until I realize that I have to start the whole thing over again. And this is on the singleplayer mode, sharpshooter in Casino Vault could even make the undead heart pump.
