VVVGamer has posted an interview with Michele Caletti, Director of SBK X.
Quote:
VVVGamer: "I can imagine what’s the biggest challenge in making this game so far what has been toughest?"
Michele: "For us, SBK-X to keep balance to the arcade mode and the simulation mode because we want them to not to give the impression that it was a simulation game with some accessory parts and neither to give the impression that there was turned completely to an arcade game. So we had to balance the importance, the content and the features between the two main branches, so that has been quite a challenge."
