Yes, neither are real ports because Crystal Tools is a cross-platform PC-based engine. It was initially an engine optimized for ps3, but it further added X360 and Wii support.
However, if some people here say that the ps3 version is not a port whereas the X360 one is, then I say with the same logic that the ps3 one is also a port.
If you ever add the choice of "neither a port" put me there, otherwise leave me where I currently am.
