I agree with Alex and Kevin. If we had to wait for all details to be simulated, we'd never have had any simulator to date. And yet, twenty years ago, young me was having fun and excitement and falling in love with motorsports by playing Geoff Crammond's GP2 with a flight stick. Likewise, SCE was a valid, fun and exciting sim even before dynamic track rubbering was introduced. Wet weather is a huge part of car racing, and it's doubly important for fans of Ayrton Senna, such as myself. I'd also rather have a simplified system than no system.
