The current site tournament is GSL 13 (Gamerscore League) where members come together and compete for the overall highest score. It goes for 10 weeks this year and is the site's most gruelling tournament. We have about 3 weeks left.
I haven't played the latest Sherlock Holmes game yet, but a few members here have mentioned that they thought it was pretty good. I'm currently playing Sherlock Vs Jack The Ripper, the oldest game in the series.
