Oh I love stuff like this. I remember an old PC game called Indianapolis 500, I soon got bored of driving round and round, but discovered it had some excellent crashing, so me and my friends would play our own game of trying to wipe out as many competitors as possible in a single crash. Was great fun.
Then later came burnout of course, that had a massively fun crash mode.
Gran Turismo is also a favourite of mine, but they never implement proper crashes or let their sponsors cars get messed up, which I thought was something missing from the series.
