Why some real classics like Crash and Spyro titles are not compatible with PS Vita?
Why such high selling games as Gran Turismo or Tekken 3 not even on PSN?
Because neither Sony or the respected publishers want to pay to transition these games over. They just don't feel that there's enough profit for them to do so. But I'd love to see Tekken 3 make it over, it was one of my all time faavorite fighters on the PS1.
