Summarise a Board Game's Rules to Explain to a Friend

You love the game. Your friends will too, if they survive the half-hour rules dump first. Name the game and this builds a teach that opens with the win condition, covers a turn, and gets people playing fast, holding the fiddly bits back until they're needed. For anyone introducing a board game to a group who've never touched it.
