The game I've been waiting for at least 15 years is finally out - VTMB2. It has its flaws, but surprisingly, it's not as bad as it could have been. They didn't half-ass it; it's very atmospheric and sometimes surprises you with how unique its locations are.
The most amazing one is an underground city that formed after a fire. In the game, the city's Prince decided not to clear the rubble after the fire but to rebuild the city on top of it. This created a unique location where all sorts of secrets could be hidden away from the citizens.
But the coolest part is that this story isn't made up! The game is set in Seattle, a city that actually has the ruins of an old city beneath it, which was damaged by a fire in the late 19th century.
