PixelJunk developer Q Games has said that it's not likely to port any more games to Sony's PSP handheld due to piracy.
The PixelJunk series has been exclusive to the PlayStation Network for PlayStation 3, with the success of releases PixelJunk Monsters, PixelJunk Racers and PixelJunk Eden prompting Q Games to port a version of Monsters to the PSP.
But founder Dylan Cuthbert has said anti-piracy measures are unlikely to stop any hacking of his games, and he was shocked to discover users openly discussing piracy of Monsters Deluxe in chat rooms.
"I don't think we'll port anything else to the PSP, we have to see how [PixelJunk Monsters Deluxe] does as there's a lot of piracy," Cuthbert told fans via Twitter.
"Because Monsters is such a good fit it is being pirated I think, maybe the pirates will buy the full version out of guilt?" he added.
Asked by a fan if the company could combat piracy by adding serial numbers to code, Cuthbert said that "unfortunately the pirates could just hack those kinds of things out," and that "a PSP demo is in the works but I don't think it makes any difference to piracy."
"It was a shock to login to a [PixelJunk Monsters Deluxe] chat room and hear them talking about how they were all playing ripped versions," added Cuthbert.
