CityVille Valentine's Day mini-game + prizes: Everything you need to know

In honor of the day of love, CityVille on Facebook has rolled out a new Valentine's Day mini-game, where you create custom virtual cards and send them to friends. Of course, what good is sending cards if you don't get any in return. You'll also collect as many custom V-day cards from your fellow CityVille players, which will give you access to a slew of V-day themed prizes -- all of which, IMHO, are pretty freakin' adorable.
