Anyone who's a fan of Star Trek, Firefly, etc, and likes (or doesn't mind) challenging games should play indie PC game FTL. It's a really fun and well-designed pseudo-Roguelike about managing a small spaceship as it races through space fighting and exploring, and is only $10 on Steam or from http://www.ftlgame.com/ . I've seen several people describe FTL as "the game I didn't know I always wanted", and I felt the same.

It's also good practice for risk and crisis management - there's a lot of literal putting out of fires :).
