Even though it's not made by Rockstar it still shares some of the creation traits. Outside of that the game does have challenges and options that GTA doesn't. Things like learning different martial arts fighting moves and cognitive brain teasers that keep you sharp on and off the game. It's worth playing but doesn't have severe re-playability...so just rent it.
First there is a lot of cussing in this game. No where near GTA or a knock off of it. You will rarely use a gun in the beginning until the end and if you do obtain one you dont get to keep it. Fighting is very simple should of been more combos and fighting styles.
