As a long time PC gamer I have fond memories of the Cannon Fodder franchise. It was a game where you controlled a mini group of soldiers that either lived or died on deadly missions through the jungle, desert and snow. If they lived, the characters (all named) moved on to the next, if they died, their grave was added to the list of the fallen. Because of this, you became attached to the little guys, and did everything in your power to make sure they survived to see the next battle. Despite what sounds like a sobering game, it was incredibly entertaining - and actually quite silly.
