This is a great game...
Moving around is not the only problem with Sleeping Dogs, hand-to-hand combat is another. Firstly, there's a lag in the combat especially when you're fighting a large number of thugs (gangsters). The combat is not as "free-flowing" and crisp as the Batman Arkham Series. Sometimes when you hit the left mouse button, it doesn't do anything -- you'll just stand there like a dummy, not until you shuffle your feet for a bit (by hitting the 'w' 's' 'a' 'd' keys). And to ensure that you would be able to block the melee attacks, the safest way is to click the right mouse button repeatedly (and also to turn your body quickly to face your attackers). Second, though the game allows player to learn a wide varieties of new melee attacks, the only place where those move could be executed beautifully is on the sparring mat at the "dojo". It's really a pity. It'd be interesting if the developers could release a video featuring those fancy moves (as played on a PC) in one of those drug busts.
I would imagine that Sleeping Dogs would fare much better on the Consoles, though for some reason, I'm not seeing that here on Gamespot. I would have given this game (the PC version) an 8.5 but since it's broken and crippled, I'm only giving it a 7.0.
Update 1: The latest patch fixes the mouse problem -- the camera is now fixed, and the control seems a little more responsive too... There are still other minor problems with the control though that could be changed or fine tuned, but those won't interfere with the gameplay. So it's all good now.
Update 2: I've also noticed that countering now is a bit different. In order to effectively counter the melee attacks, you click on the right mouse button and then immediately follow it up with the attack sequences.
