Oh I studied Dragon's Lair quite a bit before I threw down two quarters to play. Punch*Out was .50cents too but I'd just wait til some dummy lost on the second fighter and I bought a rematch for 25 cents. Same thing with Cliff Hanger, continues were only one quarter. Cockpit games (Pole pos, Spy hunter) were also 50cents, so I'd wait til I went somewhere that had the upright.
