Quote from Inteview with Fuudo(Japanese top VF player)
Tetra: What do you think of SF4 gameplay as compared to VF5?
Fuudo: SF4 and VF5 requires different mindset to play. It is important to understand and make use of all the set ups for SF4. Also SF4 requires alot of techniques to play effectively. Whereas VF requires alot of yomi and how you can find other players bad habits.
Tetra: For example, Itazan doesnt have high level of techniques and execution. He usually input 1 throw break but he excel as a top player for VF5 due to his high level of yomi.
So VF is all about the mind game.
