If you play trivia games, you know that sometimes the answers can get outdated, such as "Which movie holds the record for the most Oscar nominations?", depending on when the game was published. People become angry or discouraged at such outdated answers, but why not correct them yourself? You don't need the publisher to produce a whole new version just for you. If you know the answer is wrong now, you could break out a label printer and just stick the right answer on the card, over the old one. Would that be so bad? Yes, you'd be "defacing" the game, but would you rather have a game card that's pristine and wrong, or one that's right?

PS - Somehow it gains more weight when someone else prints things for you.
PPS - I can see this becoming less of a hangup in the future.
