There's a demo on Steam, IIRC. I beat the game back in the summer, the plot pretty cool in my book, got me immersed. Sleeping Dogs is one of the very few games that came out this year that I've actually managed to finish. The only other I recall being Spec Ops: The Line, which had a spectaculary surprising and fine plot. Anyways, SD has a nice enough plot (although the finale was a bit of a letdown, and overall the game is a bit short when you compare it to, say, the GTA series), looks beautiful and is quite entertaining to play. Driving physics are arcadeish, but not an abomination like Saints Row 2. Feels a bit strange at first, but I got used to it pretty fast. The melee combat system is especially fun, the level of both finesse and brutality is glorious. A title worth checking out, IMHO.
