You can play SC:DD in about half an hour, and will probably want to play at least two sessions back to back. I've played with children as young as 7 years of age and hardcore adult gamers. SC:DD is designed for 4-8 players, works for 2-12, and unlike most large games, actually gets better as the teams get larger.
You can think of it as either a hardcore party game or the world's most casual tabletop RPG. Playing it feels like being on the bridge in Star Trek, but with laughter when things don't go your way. Space Cadets: Dice Duel is a team cooperative space ship combat game.
