I started in on Hotline Miami yesterday. And now that I have, I feel I can state this without any presumption.
On the game’s webpage, there’s more than one testimonial blurb about how this is the game Rockstar always “thinks” they are making in Grand Theft Auto. I am sure they only mean that in the most joking of ways, but I think it bears talking about. If you are familiar with both GTA (specifically Vice City) and Hotline Miami, it is impossible not to think of one at the sight of the other.
But Hotline Miami and Vice City are very different games. They do different things.
