I have to say it's faaarrrr above my expectation!!!
This is review is based on first 2-3 hours of the game. Just grabbed the game today.
Gameplay : The simple way to describe this is, GTA open world mechanism + Assassin's creed ( for climbing-thing and suspicious-thing) plus Sin City art work!
Graphic: the graphic is quite good, haven't got any problem with it. I can put it on par with GTA. I just love the art work! Some polish may needed. But it's good.
Sound: Pretty average, the dialogue on the game feels a bit flat. But the city still feels alive.
And I have to say that the control isn't that good for me.
That's it for the review.
Final words: It's a good game, worth every penny.
so 8.5/10 for me. I could've given it 9/10 if the control is better!
