It may be a GTA_IV wannabe but it does look exceedingly violent and of course the scenery is different.
There are those who compare Saints Row The Third with GTA_IV as well but the difference is chalk and cheese, SRTT is a helluva lot more fun for a start. Same rules may apply between GTA_IV & Sleeping Dogs.
I've also got an Xbox 360 Wireless controller, well, two of 'em tbh, you do really need two to play the two characters in the more recent Lego games.
Both powered, on V_R's recommendation, with Venom battery packs. Superb
