I have been a fan of this series ever since I played the original driver. Driv3r (Driver 3), my favourite of the series, was a fantastic game and this new one seems to have taken several steps back. It's lost everything that made the last game cool.
Although the game starts in the 70s, most of it is played in the present day, which is not cool in the slightest. The soundtrack is alright, but not as interesting as the last game. The cut scenes look very good, but the plot is terrible. The graphics are no better than in the last game, although sparks flying from hanging bodywork are a nice touch.
Gameplay hasn't moved on at all. The on foot controls are now very basic. The character cannot jump, climb or swim, when he could in Driv3r. They can be very frustrating when you want to get things done quickly, like when you're playing against the clock or are in a firefight. Getting into vehicles is especially annoying. The driving is much the same as it's always been, I found it frustrating that the throttle is just an on off switch, making progress jerky if you're not going flat out.
There is now a garage feature, enabling you to store one of each type of car in the game and improve them. This is quite interesting at first but soon becomes tedious, with the same options available for every car. There are also a number of side games, but none are especially interesting.
The police are rubbish. I like the way you can escape if you change cars when no one is looking, but apart from that the system is terrible. The AI is awful, all you have to do is drive down an alley and they suddenly can't find you.
The Wii specific controls seem to be an afterthought. Driving controls are poor and the on foot shooting looking controls don't really work. I'd rather have a conventional controller.
In summary, the game has lost every thing that made it interesting in it's own right. It's trynig to be a clone of GTA and it does a terrible job. I recommend you buy The Godfather: Blackhand Edition. That's what I'm going to do!
