I know there is definitively a role for HiFi Simulation–from my perspective it should probably be for cognitive, not skill development. I have always believed skill and scenario training can be done with low-fidelity simulation, preferably in the place you will actually be playing. Well, Jon Gatward is the master of In-Situ Sim. He now has a website that breaks it all down. If you care about training and education, treat yourself to a gander.
