Have you tried fighting someone with a sword? Well, that's what Vavra means by realism. It's action over abstraction. I don't agree with him that there's only room for one design philosophy, and least of all i don't agree with him that an action based simulation makes other forms of RPG combat redundant, but in itself there's nothing wrong with simulation through direct action as a design principle.
I mean, we have no problem calling this a simulation:
What's the difference here exactly? Stuff like Arma too follows a similar design principle, and i don't seen anything wrong with that either. Aren't we making the same mistake as Vavra in claiming our design ideal in regards to combat in an RPG is the "only" valid one?
You can go out on a car and test it, the models, the drag, the torque, the physics, are all measurable and quantifiable, how it should handle on a track, you put a wheel connected to your computer and you can drive the car like it was the real thing, or as close to it as you are going to get.
Sword combat with medieval weapons is just an aproximation, none of the experts we have today ever fought in medieval times, didn't live in those times, never fought with risk to their own lives. What we have are people trying to look cool in mock combat, with their own interpretation of what some books or paintings/drawings described as combat
What we have in the game is a bunch of animations that you click a direction and attack, a stamina bar that depletes and fills up serving as health, how is that realistic or a simulation?
