It held up for me. I played a lot of Stratego with family and friends as a kid, but there was one friend in particular who routinely wiped the battlefield with my pieces. I couldn't understand how he so consistently beat me, and as an adult I was able to 1) reason more deeply about the game, and 2) quickly learn deeper strategy from the Internet. As a result, the game is even richer now to me than it was in the 1980s.
