For me most of the fun comes in making games behave unrealistic or unintended (whether it means modding the game, or exploiting it - single player only games not online games). Like I loved how in either Euro Truck Simulator, I got off the road and got off course, pretty sure a real truck might of blown up by the time I got it back on the road. Flight Sim is another one that doesn't let you crash under specific settings. I do hope for more simulators though. We technically have some programming "simulators" for Assembly programming puzzlers.
