Aside from the act that it's set in Miami (well...) in the 80s and involves organised crime it's fuck all like it really.

It's about as much like Scarface as San Andreas was like Boyz in the hood (ie: slightly)

I couldn't care if it was about Scarface or not, aslong as it offers different gameplay to similar games, Like SA or enhances the genre in some way it's cool.

Being about Scarface is just a classic bonus for me...
