Completed this the other week, as I mentioned above I kinda liked (some of) Driv3r so at £7 it seemed too good an opportunity to turn down.
And well, what can I say, I kinda liked this one too

The sections on foot are much improved, it's a lot less clunky and altogether a more well put together game. It's shorter, and the storyline is weaker, but with fewer glaring flaws it's one of those games you can sit back and play for a couple of hours in the evening with your brain disengaged. They've obviously taken a leaf out of Rockstar's book and tried to make it a little more freeform, with multiple missions available at once, cash earnt to buy upgrades etc. Sadly that area of the game is a little underdeveloped (or at least, there's little incentive to spend much time on the non-story missions).
As you'd expect from the Driver series, the best sections are still those where you are behind the wheel, with standout missions including a section where you have to tear around the city diverting a motorcade into an abush, and 'fixed' races where your job is to ensure that another car wins by disrupting all the other competitors (queue manic Carmageddon style trips the wrong way round the track!).
The game was fairly straightfoward on normal difficulty, and I have to say that in particular the sections on foot were made rather simple by having health packs seemingly every 10 yards through the levels. Still, with the game using a checkpoint save system, that's arguably better than some of the GTA series, where a moments lapse or piece of bad luck can see you back to square one.
Graphically it looks decent, and it ran pretty much perfect maxed out at 1680x1050 4xAA 16xAF for me.
So in summation, it's not a great game but fans of the genre could do a lot worse than pick it up. I recently reinstalled GTA3 and loaded up my most recent savegame (August 2002!) and found that actually, drIVer is arguably better in some aspects. It's nowhere near the quality of Vice City or even San Andreas, but there's enough there to keep you playing through to the end.
