Again, I'm not so much talking about how "sensations" are simulated but rather what the aircraft (sim) does on the ground. For example, it would normally be very difficult to ground loop a transport category aircraft (or any tricycle gear aircraft for that matter) on a dry runway with good braking action but in some sims I have had the "pleasure" to fly, it was very "easy" to do. A take off abort with an engine failure would sometimes result in ground loops resembling ice skating figures. Same for significant cross winds on landing even with everything done right (de-crab in the flare, increasing into wind aileron during roll-out etc): Sometimes the thing would just ground loop just before reaching taxi speed. Happened to me (and witnessed others do it) in more than one sim. Never had a problem with crosswinds in the real aircraft....
