I would pick Battletoads (1991) on the Nintendo Entertainment System. You progress by defeating an enemy and avoiding dangers in the environment. It was notorious for its difficulty-a wrong move sends you back to the beginning of the level or the entire game. This game has no saving system or password features. Modern games usually have autosaves and checkpoints.
What old-school game do you think is more difficult than modern games in your opinion?
