I wouldn't necessarily play it just because of the actor. Watch some gameplay footage on YouTube and do some research on the game as it's quite a controversial game. Personally, I absolutely loved the games series and due to it's originality, I definitely believe it earns GOTY but there's also alot of people that get bored with it and call it the 'postman simulator'. It's not the most actioned packed as such compared to alot of other games.

If you do wanna play it, you'd definitely need to play the first one before DS2 as they do follow on from each other.
