Dragon's Lair and Space Ace. You want to talk about tough games. You had to spend a butt load of quarters to figure out which move you needed to do and at which particular time. Then, when you thought that you had it all figured out, you had to do the whole game backwards before you could save Princess Daphne. And you did all this just because it was a cartoon video game (and Daphne was wearin' a see through nighty. Man, we needed help.) And Space Ace was the same damn thing, just in space.
