Metal Gear Solid 4: Guns of the Patriots
If there’s one old man who has been more beaten and broken down than anyone else I’ve seen in video games, it’s Solid Snake in MGS4. Technically Snake isn’t old—he’s rapidly aging due to being a clone of his father, Big Boss, and the FOXDIE virus is slowly killing him. But even aside from the unbelievable abuse he physically goes through (microwave room, anyone?), Snake is old. He winces and touches his back when crouching; he’s cantankerous and impatient, and he’s got to deal with all of this while trying to stop a madman bent on world conquest. So much for a quiet retirement in Alaska.
