I've never found a rally driving game that handles like a real car. The physics always seems off - in Dirt Rally (the last one I tried seriously, and the one that everyone raved about), the car still seems to have the old physics of pivoting around the centre of the car, but whatever, it's miles off. The mini cooper in there is about the same power and weight as the Skoda Felicia that I drove, but it behaves nothing like it. I wish it did, as I no longer have the money or time to do anything like this, and if it felt anything like the real thing I'd have a fun hobby to take part it. But I always get hugely frustrated when I can't get anywhere near what I used to be able to do - place the car with precision on the road, get a good rhythm up and start to flow, and don't seem to be able to adjust to the way the cars handle in these games. I'm sure some of it is that you can't feel what's going on - through the seat, steering wheel and pedals - in the way that you can in the real thing, but I think there's more to it than that.
Forza was pretty different - even playing it using just controllers showed that it was handling much like a car would on track (I've done some tarmac rallying as well, so I'm used to the limit on tarmac as well as gravel), but I'm not really interested in circuit racing, alas!
