I had the opposite experience as a kid. I'd lose to my father in Scrabble over and over, but I'd continue to play against him anyway. I think I just enjoyed playing a game that was meant for adults. As I got older, I started to win more and more, but for the first year or two I don't remember winning at all (although it's entirely possible I'm not remembering things correctly).

Still, I like to think losing at games as a child taught me to be focused less on the act of winning and more on the act of playing the game. It's a quality that very few people appear to have, even as adults.
