New on RPGNow/DTRPG is Baker Street: Roleplaying in the world of Sherlock Holmes. Sherlock is missing and presumed dead in this rpg and your characters take up the slack as they solve the 'most baffling crimes in history'. Mystery is always a tough sell in an rpg and I've never seen it done as well as the Gumshoe rpgs have. Baker Street looks very intriguing, can't wait to see a review on this one.
However, I would have to update it for my modern sensibilities and mix it with the punk-infused version of Holmes from Guy Davis' indie comic Baker Street.
Holmes doesn't have to be confined to the Victorian era.
