Most definitely the best expansion to Square's free-roaming game Sleeping Dogs. Wei Shen's degradation in the police's ranks freshes and spices things up for the game. If you haven't had enough of Sleeping Dogs, get your hands on this DLC.
Yes, Year of the Snake is a better expansion than Nightmare in North Point. Still, the downloadable content is plagued by the same problems as the original game, and its short length makes sure you'll never get dragged into its story.
