Cthulhu: Death May Die has an insanity track. When you advance on it, you unlock special abilities and get bonus dice. However, when you reach the end of the track, your character succumbs to the madness and is eliminated. It often creates very tense moments, you need the extra power to kill the elder one but if you push too soon you lose.
Angola, by the Ragnar brothers, has lots of clever mechanisms including one that is a form of sweet spot. I think it is thematically accurate too. If your faction starts losing then its allies (Cuba, South Africa or the US) will supply more sophisticated weapons. If you carry on losing, though, they will take them away and you are probably doomed.

This is one of my favorite mechanisms from a really fun game. I too immediately thought of this one!
