One of the things that sets Wraith apart from the other World of Darkness games is that it actually achieves what it sets out to do. Which is to create a setting for ghost stories. Most any ghost story you care to imagine can be recreated with Wraith: The Oblivion. On the technical side Wraith delivers a system that actually approximates what you see in ghost stories and movies. As for setting, the Stygian Underworld is quite compatible with most ghost stories and doesn't need to intrude on the Shadowlands for most campaigns.
