First off: If you're at all into the theme of the good ol' gangster time, this game is definitely fun to play. It's a a nice take on the Gangsters approach and is good fun. At first glance, and for the first couple hours, the game is great fun.
Unfortunately it lacks depth later on – you find yourself just „tagging along" the storyline and basically just waiting until you're ready to click the next building so you can get into the next in-house-fight.
The fights are quite well done and entertaining.
There's a lot of potential and I am looking forward to a sequel with more depth: More freedom of choice & more options on the city level, with a bit more depth in your gangster's progression (e.g. RPG-elements).
