Virtua Fighter is actually quite different from Tekken. As a matter of fact, I think Virtua Fighter is a tad closer to Dead or Alive than Tekken in mechanics and gameplay. I think both games are excellent and can coexist. We need more 3D fighters on the market anyway.
I'm loving the game a lot. It's amazing how nicely everything works there. It's a really smooth experience with the dedicated servers. And the gameplay is legitimately fun (both 2v2 and 1v1). I hope they make a lot of money because they deserve.
