Not true....both model railroading and train sims try to recreate the real deal, so to say they are nothing alike is simply incorrect. Besides, the real deal isn't part of the comparison chart...only models and sims...which are very simular in purpose but using a different method of modeling the real deal. Saying that it's an apples to pears comparison doesn't fit...and whether it's a useless excercise is strictly a matter of opinion...
Blimey ... the whole topic is a matter of opinion. We are not talking science here do we? Ever tried to pick up one of the locomotives in Trainz with your hands? It is apples and pears my friend. You mistake my comments for them criticizing the simulator. I am not. One is not better or worse then the other; they are different in the core.
