I've recently finished the campaign for Sleeping Dogs. Roughly 16 hours with some messing around with side missions before I started focusing on the main story.
I originally tried playing it on Xbox 360 but didn't like it because of how different the driving is compared to GTA IV, which I was playing a lot of at the time.
There's quite a bit of melee fighting action, which is executed pretty well for a GTA clone. But (IMO) not as good as Batman or Shadow of Mordor / War.
The atmosphere, story, acting are all pretty enjoyable, and I think the graphics hold up well. The Definitive Edition (which I played) may have updated graphics.
Definitely recommend giving it a go.
It's a crowd favourite over at /r/patientgamers/
