One of the strongest selling points of the PSP was its ability to play PlayStation games, but PlayStation Vita Sony marketing VP John Koller believes that this was also the main reason behind its failure.
"The issue that happened with PSP is we got overrun with ports," he argued
"It became very difficult for us to define what made PSP unique. The content development became a bit unstructured or decentralised, in that we got a lot of content that was on PlayStation 2 and got thrown over to the handheld."
Koller explained that Sony wanted to frame PSP games as "console-like games on portables" and that it has guided developers to that end. Interestingly, Koller admits that the company is still promoting a similar image for PS Vita. "The messaging is similar, but I think the output is going to be quite different," he said.
