What do you tell people about this game? (if you have to)

As much as I support the "No seriously I can't tell you anything about it. Trust me, just play it. It's amazing" approach, some people need a bit more of a reason to buy and play a game. What would you tell someone if they needed a bit more convincing that the game is for them? Is there anything specific about the game you'd tell them? Is there anything you'd show them? I'm just curious what other people's answers are!
