Don't just rely on the metro to get activity going in your building, get a parking garage! This parking garage is an animated building that will allow more people to spawn in your building than ever before. On the plus side, unlike the metro, you can build as many parking decks as you like, allowing for much more opportunity to show off your fantastic complex than ever before.
