Mary was curious to see what Tony was like in his prime, when he was a bit reckless and spent money like it was nothing. On the ship he seemed a bit more subdued, perhaps because there wasn't anything to throw money at - and he technically didn't have any here.
A smile crossed her lips. "I would rather play against people from the ship than complete strangers," she said. Honestly, she didn't think she was good enough to go up against someone in a truly competitive game. A mostly friendly game would be a better start.
