I think I'd like to play a game that punished me for being good. Mainly because I have this fantasy in my head of playing a guy who does get pounded into the ground, day in, day out, and just gets back up to face the difficulties. Who at the end of it all has lost everything that was dear to him personally, but keeps on doing it because he knows it is right. And then, at the end, dies alone and to be forgotten, but the world lives on better than ever.
Something bittersweet. Not enough of it out there, I think. I won't say games are devoid of it, but they may force it a bit too much. And pop it up only at the end.
