Annyyywaayyy, I once watched 4 hours of Mafia 1 and it looked like someone took the GTA 4 approach of "Hey *****, drive over there and do some shit for me" and made it into a game.
Mafia 2 looked better, but then I didn't watch a lot of it.
I watched what I assume is the video that led to the OP making this thread, as the comments there mirror his reaction (I'll link it down below). Its 12 minutes, and I'd better get a cookie for that, because I HATE IGN commentaries.
My impressions:
The Pros - It looks like a fun third person shooter. I like third person shooters, though I have to agree with people when they say that it looks a lot like the more recent Splinter Cell games. You have a lot of different executions, I think there are several unique ones for each gun. And it's a nice little touch that you are ambidextrous.
As an open world game, it looks gorgeous and is packed with people. New Jersey looks like a very interesting place to be. It seems to reward exploration. The driving also seems nice (they have a rear-view mirror! I don't know why I was so entertained by that), but TBH I never cared about things like that. There's this cool minigame where you drive like a crazy man in order to scare the shit out of the target. That's right up my alley, I hate having to drive all proper like.
The Cons - It's definitely not a Mafia game that Mafia fans want, but is it a con? More on that later.
Anyway, I couldn't really find any cons, at least from the gameplay. I guess you could claim that is generic, and I wouldn't blame you. You could also say it's not very realistic, and from what admittedly little I know of the Mafia series, I think some fans would have a problem with this. The game goes out of it's way to make cars explode, and it kind of rubs me the wrong way. There was this one part where 4 guys in a car were shooting you with Tommy guns, and one shot from your pistol to their wheel made them do a 360 flip in the air and explode for no particular reason. The same goes for a lot of the hand to hand takedowns. They seem overly violent and not at all stealthy. I assume its from this that many people are claiming that it copies GTA. Is it a legitimate claim? Depends on you.
The Thing I Would Kinda Prefer Not to Talk About - So. This game has a mixed race character.
Sigh.
This is one of the bigger complaints I have seen. Not that the dude is black, but more of that he isn't Italian. The game is called Mafia, the series has always been a member of the Mafia, but in this game your job is to... overthrow the Mafia?
I thought it was a cool move to have a mission in Mafia 2 where you kill the protagonist of the earlier game, but isn't this taking it too far? There is no law that says that the game has to be similar to the last ones, but I am just saying that I can understand why a lot of Mafia fans are upset. They wanted a Godfather experience, instead you get the, uh, I dunno, whatever the organization you lead is (Is the "black mob" a thing? I never heard of them).
The character's race could definitely lead to some good storytelling, and the devs themselves claim they will tackle racial issues. I hope they don't do it too heavy handed.
All in all, while I disagree with the notion that this will be a bad game, I can totally understand why fans are upset.
