Just been playing the demo on the xbox 360, and it's everything I hoped for. The detail is amazing, not just on things like bullet holes and car damage, but stuff like drinking a bottle of cola or having your car washed and refilled at the gas station, or even flushing toilets and turning taps on. The simulation driving is really fun too, it makes driving at high speed quite a challenge, and peeling away from a set of lights leaving a trail of thick tyre smoke behind you is awesome. I was really worried that they would ruin Mafia, and I'm so glad it doesn't seem like they have.
