The harder you throw your punch in real life, more damage it does inside the game.
Punching form matters, real life fighting technique matters
Throwing combination strike matters because.... It gives you the 'power'
Player need to be able to achieve fitness results using VFC
Player need to be ale to learn fighting technique and get better at it playing the game
Player can use real world fighting technique, but it doesn't need to look the same as real world, because virtual reality should be better than reality
Create VR fighting as it's own genre
The 'dynamic' of real world fighting should be replicated as much as possible inside VFC, but the 'stamina' requirement should be less emphasized (as most people does not aspire to acquire an athlete level stamina)
