I'm currently playing Sleeping Dogs, which I really like.
I played all GTA's ever made, so I was sceptical if this "clone" would have the same quality. Actually, it's not a clone, it's a sandbox game infused with kung-fu. It also offers a different location than usual, namely Hong Kong.
The kung-fu isn't just a gimmick, it's an integral part of the game. In a lot of situations, I find myself kicking the ass out of gangsters with machine guns, and finding it more convenient than shooting them. There's also stunts like hi-jacking a car while driving yourself by jumping from the door. You can also use a lot of objects or environments as a weapon, like most fighter games.
Play the demo, it blew me away.
